You are one of the finest teachers I have come across and I used to be one. Such clarity of logic and sequence of causation is a gift. With greatest appreciation, please keep this ability going strong!
UA-cam should have invented a DONATE button on every video. Why is this not done yet? Why would you not donate a buck or two for a good video that helped you? Some videos make money by views but most usefull videos don't get that many views but are gold to those who need it.
i know you wrote this 3 years ago but this guy has saved people thousands in labor costs and giving even 5 bucks would make his day and wont effect youre life much at all... i do agree there should be donate button on every video because most useful ones are not getting much views unless people need to find out "how to" something
Sorry to be so offtopic but does any of you know of a tool to log back into an Instagram account? I somehow lost the login password. I would love any help you can offer me.
Man I'm a mechanic myself and your videos have helped me so much with my car. Thank you very much for your time of making them. A lot of people including myself are new to BMW's and you help ALOT man.
I just started throwing a P0174 too. Smoke test was good, MAF was clean, recently rebuilt my DISA. All the usual stuff was good. Turned out to be the air pump control valve and gasket. So keep that in your diagnostic arsenal for future reference. And it's an easy fix/replacement too (beside the exhaust manifold near the front).
You are Hands Down The Best instructor Ive seen in years - You make trust worthy eye contact somehow and you can easily sense you know your shit. The way you describe or note any relevant details, tips or cautions with detailed why's are very much needed to create a solid longterm memory. You should instruct in tech college or an automotive school. One that pays what you are worth. Video and sound guy ~excellent job as well. TY for Being and Doing.
@@50sKid hey man thanks for the video. Hearing a sucking noise from around the intake manifold. Not sure if it is normal but. Would a bad disa ring cause this?
Excellent video. For the other 5% of cases, there are also three less common o-ring failures you might want to check before buying a new MAF: Dipstick tube upper o-rings (x2), fuel injector lower o-rings (x6), air distribution piece o-rings (x6). Also, if you have a 330 then you have a vacuum actuated exhaust. This is a 3.5 mm line that runs down from the back of the intake manifold to a vacuum canister and through the firewall to the rear of the car. There is also the throttle body gasket and idle control valve grommet, which may leak if reused and not seated properly, respectively. Finally, if your lean codes are set at highway speeds rather than idle then it is more likely to be a soft failing MAF than a vacuum leak.
50sKid Yes, the dipstick upper o-rings are on the dipstick rather than the guide tube. There are two of them measuring 9 x 2.22, which is smaller than the lower o-ring that goes around the dipstick guide tube and sump. My upper o-rings were not leaking, but looked worn and flat compared to the plusher new ones and offered greater resistance to removing the dipstick from the guide tube i.e. a better seal. Obviously if you do not check your oil weekly like me, then your upper o-rings will be less worn. It is always good practise to replace the lower o-ring when pulling the dipstick guide tube. For proper installation, lubricate the new o-ring and put on the dipstick guide tube. I have heard they can easily tear and give you a vacuum leak if you put them on the sump and force the guide tube into place. Tolerances are tight so it may take you 30 mins of wiggling to properly seat the new o-ring even when lubricated.
clabcon Yeah pulling that dipstick weekly'll sure do it! Mine sticks in that tube like an SOB and I gotta pull hard on it. I've got about 170k miles on my car and the dipstick tube o-ring was in quite good shape--I replaced it in my CCV videos that I recently did "just cuz," but it honestly was just fine. I think it all depends on if you've gone and left the o-ring in the pan and tried to shove your dipstick tube in that way. But, to anyone reading these comments, Harbor Freight sells a pack of Metric o-rings for $5 and it has the proper size.
50sKid Almost 120k miles here and I have the revised design single walled dipstick guide tube. The damb dipstick snags on a ridge in the bottom and has to be rotated 180 degrees to remove! I think the second batch of these was made in China instead of Germany...
" if you have a 330 then you have a vacuum actuated exhaust. This is a 3.5 mm line that runs down from the back of the intake manifold to a vacuum canister and through the firewall to the rear of the car." Ah, interesting - the pipe is well cracked on the end of my one where it connects to the exhaust. Suppose it's worth me cutting that off a bit and getting a better seal (or just popping a screw in it, etc - my exhaust butterfly is completely seized so it's not doing anything) before I start tearing the engine bay apart....
Your Character!... Your compassion, Your love, your crystal voice simply made you one of the best coaches around... You are a born giver... keep up the good work and may God bless....
I know this video is 9 years old and it’s been a savior for my ongoing problem. Finally I found the issue with my E39. Thank you for your help and reasoning.
Picked up my first BMW a week ago... Totally different from my old Pontiacs and Jeep's. Found more problems than I expected, getting better thanks to your videos. Great job appreciate em.
Is there a trick to getting the bottom hose off, both clamps are kinda blocked and there’s a rip in it, or do I gotta remove that brick looking piece in the way?
You make some of the most well thought out, complete, and understandable how-to car repair videos on UA-cam. I will use this later to diagnose the codes on my '05 325i. Thank you.
Dude, you're a hero. I've owned my 325Ci for 7 years, and you've helped me through a lot of jobs. Just had these codes pop up in the last month and need to have a look around. Hopefully it's one of the easier problems to fix, I've put off the CCV for so long. 145,550 miles probably on the original CCV!
seriously dude.... I wanna ship you a fucking 12 pack. My BMW has been running like shit for years... So much so I was gonna sell it... I fixed everything.... MAF, all the hoses, all the boots, the Disa.... Never knew about the oil separator hose... You made my car start back up like normal, after 2 hours of trying to get the damn stupid ass BMW connector off, hate those black squeeze ones... EFFIN A++++++.
50sKid hi have a 318i e46 with p0171 code. it's a m43 engine and im located in France and it gives "problems de transmission du carburant". I need help
i'm a new owner of 325i e46 from indonesia, i found your videos and this one is my fav. i have no experience about the engine, but you makes me confident to fix my own car. The most important, I'm not good in English but I can understand what you said even without subtitles. Thank you, brother.
Thank you for your much appreciated time and effort in producing these videos. I'm that personality type that needs to know how things function to fully understand the purpose and vice versa. Simple questions and answers don't quite cut it for me, as there's always a "why?". Needless to say, your videos have helped me immensely! Funny thing is I'm around guys who know a whole hell of a lot more about cars than I ever will and half the time they can't help me for crap!
Thanks a lot for this video. I had just got out of the hospital when my grandsons 2001 325xi started giving him p0171/p0174 codes. I took all the hoses I could get to off and looked for vacuum leaks. I had even taken the intake runner out to get better access to look for other leaks! Didn't know enough to look at the gasket at the time. I only knew that when I sprayed brake fluid into the general area of the intake, I could occasionally get the engine to go rich for a while. It was so tight an area that it was hard to locate exactly where the spray was impacting the leak. I almost gave up and had the car taken to a shop to be smoked when I ran across your video. One viewing of your video and I knew it was the seal on the intake runner. Borrowed an incorrect sized seal from my neighbor and managed to prove it was leaking(couldn't quite get the intake runner shoved back into it's slot-but the seal held). Have ordered a new seal and will be in next week. In any case, your video was instrumental in my fixing his car. BTW, I too broke a rubber housing taking it apart(ironically, BMW had that housing in stock for $22 but wanted $400 for the intake runner because they didn't sell the seal by itself! Thanks again!
The dreaded codes for all BMW owners. Solid video, thanks for sharing your experience with identifying the sources of leaks. Looking forward to more of your BMW videos!
You are the MAN!, thanks for your videos 50's kid. Add a donation link to your youtube page, you deserve some rewards for your good advice!!! i had this issue for years, sent my car to mechanics and kept changing sensors, and i gave up, until i saw your video. I followed steps by steps and got it fixed. I am not mechanic but you made it so easy, anybody can do it. I had vacuum leak on top air boot, my disa also was leaking and the bottom boot was also fixed with electrical tape!!!, i fix these 3 f(including the cabin filter) or less than 50 bucks!!!. Thank you for being around, we E46 fanatics will appreciate it.
This was excellent dude, thank you! Such a good explanation of the M54 vacuum system. For anyone wondering, this information also applies to 2004-2006 BMW X3 E83.
Just went through my E46 to fix a vacuum leak and update the ignition system at 141000 miles. After replacing the valve cover gasket, DISA valve, fuel injectors, and several vacuum hoses I still had a rough idle. I finally broke down and replaced the lower hose on the CCV and O-ring on the oil dipstick tube to finally get the vacuum leak fixed. Thanks for pointing out those parts as failure points. Maybe I should have started there first!
great video. One thing you can do to find leaks faster is to attach a glove on the intake boot and attach a hose to the glove. Then i used an electronic cigarette to blow some smoke through the hose i attached to the glove and i found my lower boot and the disa o ring was leaking.
Hi 50s kid .. buying this 2004 3.25i for my kid has been quite an experience. going from GM to BMW was like swiching from APple to Anroid!! Here's an idea that worked for us to put the car in great condition .. you've never mentioned a smoke test .. but it sometimes would make sense. But I didn't want to do that because I thought of a simiar test .. I bough some 16 inch punk sticks. They are meant to make your house smell good .. but they generate a lot of smoke. I started the engine then moved the punk stick nes possible leak areas. In my case it was the Oil cap leaking. No doubt why it was leaking .. The ccv diaphragm was ripped before I bought it. With your video it was easy to find and fix .. but it must have been that way a long time because the oil cap gasket had a GIANT depression from being sucked in all the time. Thank you so much for the videos.
Great video! I suspected a vacuum leak but it ended up being a completely failed DISA valve (O-ring was fine) on my 2004 330xi. Replacing that should fix my P0171 and P0174 codes along with random misfires. This video saved me a lot of time. Thank you for taking the time to make this video! Keep up the good work!
Having some difficulty with my e46 with a rough and weird idle. I diagnosed it and it came back as these codes. Im having a tough time finding the leak.
I have been a victim of all of the more common faults. You have been my go to instructor, before I open anything. I wish you a long life, don't want to be out here alone.
You easily saved me over $1000.00 at a dealership. Big thank you for this video! If you ever come to Sacramento I'd be more than happy to buy you a beer. Thanks again! My 2002 330i was having an extremely rough idle and sometimes having problems accelerating like it had no power. The engine would even cut out randomly when I was at a stop light. The problem turned out to be my MAF Flap adjuster unit, the flap was snapped off and floating inside the unit. 20 minutes of labor and $150.00 part and my check engine light is gone and my car runs like new!
Many thanks, brother... I knew my E36, inside and out. Bought an '01 E46 325xi, and the M54 engine bay has me stumped at times. I want an original Owner's Manual, and the Bentley repair manual, but your videos have been SO HELPFUL
I fixed one vac leak and made another huge one several weeks ago. Had a bad vacuum leak at the DISA valve, replaced the molded gasket with German Auto Solutions o-ring. Started the car up and it ran about 5x worse than it was. Turned out I roughed up my original upper intake boot up a bit and had a 3.5 inch split in the bottom of it. Got a new upper boot and lower one even though it was replaced 5 years ago and now it runs beautifully with no codes. I had 7 total with the P0171 & P0174 and various cylinder misfires.
Had P0171 and 174 for the last 6 months... engine just started to idle horribly and starts to die if I don't let it idle until warm (while pushing the throttle above 1k RPMs because it's sitting around 500 RPM shoddily otherwise). Replacing the DISA, ICV, and intake boot tomorrow using your videos. Thanks so much for such quality material.
Had a vehicle come into my shop with all the same issues, I replaced the DIsa valve, replace the crankcase hoses and pvc system also, the intake hose. The intake hose had its common leak, I replaced that. I then found the crankcase problems tube to the dipstick was broken, still had a problem, I then smoked the intake with a smoke machine no leaks found. After looking and looking I narrowed it down to the brake booster which had an internal leak. I tested it by unplugging it and the capping it off idle remained normal, no codes. Now I need to learn more about the VANOS repair, your videos are very informative and thank you!
+50sKid - thanks budddy, do you have any info or videos that I can look at to diagnose the Vanos on these vehicle's, it seems like I am running into alot of failures on bmw's. Again, I appreciate your time and effor in putting these videos up, its greatly appreciated.
Rick Singh Well I'm not entirely sure which are the common codes that basically mean you have to rebuild the VANOS, but this guy has a good video on the procedure: ua-cam.com/video/IBJL9AkS6Qc/v-deo.html -- I've also heard of the two solenoids on either side getting stuck and needing to be cleaned out, and those problems resulted in different codes being set (again I don't remember which ones, I'll have to make a note for my future video). What codes are you seeing?
+50sKid - I will update you when I run into another problem with one. I don't remember the codes top of my head I do get a lot of these cars for repair these days. I have my own private shop that I run, and these cars are very tricky at times to diagnose, thanks again buddy.
50s Kid- you rock! You helped me a lot by doing this video, since I learned where to look to fix a big vacuum leak(s). I just got done replacing my DISA valve and also repaired a crack in the lower boot (just used electric tape around the crack so I wouldn't have to wait to get a replacement boot). Car runs great now.
this man will make you way more confident in trying do the work yourself and be comfortable doing so knowing you have got the best instruction to tackle any job. thanks bro
I have a major problem with this video.. your clarity and explanation gives me the confidence that I can do this.. I just want to say thank you for this video. I had the maf cleaned, plugs tightened filters replaced or cleaned my car runs great it makes a sound that I don't like when I turn the car off.. Codes wont clear, time to check for vacuum leak.
Hoollllyyy smokes. This was the explanation i needed. In all honesty, this is making the fault deduction process way easier when its explained this way. The mechanics of how these systems operate. I just replaced my alternator and had to remove the air flow system to get to it, (sounded scarier than it axtually was) and aftet i placed everyhting back together, these 2 codes popped up the next day. 2 days after when i had time, i re-removed the air flow system again to make sure EVERYTHING was tightened back correctly, (and replaced my air box filter in the process) then the code dissapeared right after. Fast forward 5 days later, codes are back. So at least i know what im lookin at now after this videos details. TYSM 😊
I've used a number of your videos to help me out several times. Very clear explanation, very matter-of-fact, very informative. Thank you. I discovered a sneaky air leak... When rebuilding my DISA valve I noticed that the seal on the actuator arm was badly damaged. This is easy to overlook and is not included in the repair kit and leaks a lot of air. I purchased a standard oil seal 22mm dia, 12mm shaft, 6mm thick to fix this.
50's kid- you are the best! Its great that I am able to back to this video after four years to get a refresher. Love my '05 330xi- had it since new. Now i just have to figure out whats causing the odd rattling sound coming out of the exhaust pipes on cold starts. not too worried cuz it goes awy when it warms up.... but....
I kept getting those codes and I kept resetting them with my bluetooth scanner. I knew that it was some sort of vac leak due to the fact I would hear a whistle sound under acceleration. Now that I have time; I will be addressing these issues. Great informative video!
this man makes the best videos because he teaches you the knowledge you need to diagnose the problem yourself the as best as possible without a professional
Here's my story and it has a happy ending. About a half mile from home my 2003 530i engine started running really bad. No power, coughing and backfiring. Of course the check engine light came on and the 1071, 1074 codes where there along with some 1350's miss firings. I followed all the advice in this video and used about 2 big cans of carb cleaner trying to find the air leak. To no avail. 23 months ago the OEM fuel pump just quit. No codes in the computer when it failed. So after trying everything in this video I thought why not check the fuel pressure. I went to Autozone and thru their loan-a tool program got a fuel pressure tester. Instead of 40 to 45 psi of fuel pressure I had only 15 to 20 psi. Just enough to start the engine but nothing more. So unlike the last time where the pump completely failed this pump was still putting out some pressure. And the replacement pump had a 24 month warranty so I got a new one for free. So my point is after trying everything in this video, if there is still a problem check the fuel pressure.
You are the man! Did a temporary fix to one of the hoses until I get a replacement for it. Never thought some of them would get brittle like that. This video is very helpful! Thanks again!
Thank you after taking my 2004 530i to a crooked repair shop for an oil and transmission service they proceeded to tell me .Have a bad switch on my transmission $$154 part $4200 to fix..Small oil leak they wanted $2200 to re-seal my oil pan.. Unbelievable.So they refused to change the tranny fluid charged me $125 for checking ..And faulty I-drive to check $125 allegedly did a reset pressed 2 buttons...After doing an oil change Ac/recharge wheel alignment and installing 4 tires I bought.. Charged me $809 no lights were on in my car 1 day after driving Service engine light soon comes on ..I refuse to bring my car back to these crooks..Service engine codes read these same codes you speak about. I bought a code reader off Amazon and cleared them...I will check for some of the symptoms you showed ...Thank you
your videos are amazing. they have helped me bring an 323ci back from the dead. from check engine issues to trans issues and fluid filling. thanks again
Mate , Fair dinkum you could talk a bloke off a high ledge, a very articulate & effective explanation of air leaks on these M54 Z4 shitboxs has saved my arse big time down in Oz. you’re a deadset legend .. cheers 🍺
I have these codes now and my valve cover just started leaking. I will have the gasket replaced on those, hopefully it will fix the issue but will still inspect for other culprit for vacuum leaks you mentioned here. Very informative. Keep it up!
Hey 50's kid. I'm also a 50's kid with a recently acquired 2002 E46 330Ci Cpe. You produce awesome videos, and I've learned a LOT. The car is throwing a P2096 Post Catalytic Fuel Trim System Too Lean Bank 1 error, so I cannot get it smoged. I'm a mechanical engineer, but alas I don't have the time to DIY. I'm looking for someone like you in the San Fernando Valley who is proficient on BMW's; namely upgrading DME firmware and diagnosing vacuum leaks? I took the car into an indy repair shop and they quoted me a ridiculous $1,300 to do what I consider a costly trial by error fix; replace the two post cat O2 sensors ($500) and the ICV ($350) + labor ($450). From my understanding, the sensors cost ~$80 each and the ICV can be cleaned. The car has a K&N intake filter, and on inspection the post MAF intake boots are clean, soft, and pliable, but that's as far as I went. Can you provide a referral?
+David Rosenthal Check to make sure the O2 sensors are tightened fully. When I was getting a P2098 error (bank 2), it ended up being that the #2 pre cat oxygen sensor was slightly loose and causing a vacuum leak. I can't make a referral because I do my own work. :-)
I replaced my ccv valve and all hoses associated with it about 2 years ago after having burning oil issues, but now the car runs much better. However I did not buy all the right gaskets. I have p0171 and p0174 popping up. I have a hissing leak coming from the intake manifold gasket I believe and I will have to replace it. I could be wrong because It is important to replace and check so many things while doing this I realize, now I will have to tear it all apart again, just hoping I don't break something else! Patience is key thank you for your video.
You explained everything so nice, I’ve had a issue where a plugged in MAF sensor makes car run rough and die after a while with a EVAP Large Leak, yesterday before this video I did a smoke test and found a leak by that little hose near the throttle body, fixed and still same code and it’s driving me nuts after I’ve replaced 75% of the items you’ve said. You did mention some other that I haven’t checked that I will definitely be checking now like the o ring on the oil stick!
First of all, thanks for running more than excellent channel. On my euro spec (no aux air pump) e46 330ci, I had a whistling sound under partial load and occasional lean codes. I have since replaced my CCV, intake and throttle gaskets, intake hoses, checked the ICV and pligged ports, checked the brake booster line amd check valve, EVAP lines etc. Disa O-ring is tight. I smoke tested it with a glove over the MAF (which I also cleaned out with the designated spray) and it seemed al right, the nitrile glove even remained inflated. Still, I can hear a whistle under partial throttle/load and it will occasionally throw a lean code (both banks). Vanos was overhauled/resealed and valve cover gasket replaced at the same time. Oh, and both O2 sensors are new. I'm out of ideas, please chime in if you could. FPR vacuum lines maybe?
A big thanks for your video here and the one about how to remove a bunch of key components. You guidance helped me diagnose the massive air leak in my lower air intake boot and another minor hose issue. Couldn't have done it without you. Thanks!
Many thanks for a very useful video. My 1999 Z3 2.3 was throwing "O2 sensor adaption limit" codes (as per my Peake R5 FCX3 scan tool). Using this video I was able to quickly isolate the problem as a hole in the lower intake boot which was creating a colossal vacuum leak. I replaced all of the intake boot parts, cleared the codes, and all is now well.
You have the best e46 repair videos. Thank you for what you do, man. i just got a 04 325ci that sounds like a vacuum cleaner sucking air, on start up. The guy I got it from, lacks the mental faculties to diagnose an untied shoe string. lol. So, I'm going to go through the entire car. These vids will help out greatly!
You are incredible, Kid. Your videos and explanation detail is the best I've seen. I've taken my BMW X3 to the dealer 2 times with this same issue. Lean fuel PO171 & PO174. Still coming back like a nightmare. They said they did a smoke test, checked normal. First time my air filter was changed and gas manual something was changed. Second time they changed the fuel filter. I lost my faith with the dealer, looking to take to a good mechanic not, like. Hendricks BMW likes to fix one problem at a time.I bought a scanner now to help me diagnose and primarily remove the annoying service engine soon light. The concern I have now is the MAF sensor. I unplugged it and engine did not stall, like I expected. Is that a good way to test? it cause, I cleaned it, reset the light and after 400 miles its come back.You are incredible, Kid.

Your car isn't supposed to stall when you unplug the MAF, it just stumbles and recovers. That is normal. I don't believe that they did a smoke test and found nothing wrong.
Also Kid the connection between the exhaust manifold and the muffler junction. After watching your videos and performing the repairs I was still having a code but this time for some unexplained reason a P0174 code showed up. So I heard you talk about leaks around that area that can cause a problem and sure it did carnal ... the other two Ox sensors are located close to the exhaust leak causin the pitot effect drawing more air than registered. Took it to the muffler shop and eventually that took care of the problem.. Thanks Kid , Thanks for sharing your knowledge Base with us... Keep your channels running. And enjoy your weekend
Excellent information. I have owned my 2002 BMW 325csi since new, and am having the vacuum fault code occur regularly, and now a rough firing engine, with the fault code on my OBD reader indicating this problem. This is excellent information for me, and as I am a long time hobby mechanic, I will check out all the potential sources of the cause. Thanks again... ... Fortunately, my 1966 Lotus Elan does not have these type of problems.... Dual Web Carbs and "O" rings on the intake manifold are all that I have to check.... oh well !!!!
After watching this video and reading the comments i went back outside and pulled the secondary check valve out and inspected the little gasket and noticed it wasnt sitting on one of the two 10mm studs and was only sitting on just 1 smh SOOOO obviously it wasnt seated properly and i could actually see the soot on the gasket where it was escaping. Hopeing now that this is sealed off maybe now the lean codes will vanish. I have the legendary p171 p174 and also p 430....😮😮😮iam in such shock that iam afraid to go back outside and start her up...i cant believe the gasketbwas on wrong n a healthy amont of carbon on the gasket shows exactly where it was leaving...that has tobbe enough especially especially at 2500 rpms...🎉🎉🎉look at me i cant shutup!!!! ....all thanx to this video!!! 50zzz KID😊😊
great vid just fixed my buddys e46, found the oil drain tube at the dipstick was cracked causing lean codes, cleared codes and no more problems thank you again!
Thank you, great video! I had both codes P0171 and P0174 for a few weeks now and finally found the reason to be number 3 on your video. Breather hose coming from oil separator/CCV to oil dipstick looked like it was trampled... Changed it and after that no fault codes referring to air leaks.
Had the codes. Lower intake elbow damaged. Thanks for the tutorial great work!! Your oil change video helped me loads as well. Annnnnnd your instruction on diagnosing a misfire and replacing spark plugs! Great videos.
Thanks a Million my friend you helped me understand more than I knew about the Vac Sys. Because of you papa I got to understand my Car more. Following your Tutorials I have managed to trouble shoot my car step by step and fixed all of the glitches I had on my Vac Sys.. THANKS AGAIN.. If you were closer we go for some Beer... Thanks again You are a sanity saver..
This video is amazing, thanks for all the valuable info. I deep cleaned my air filter, air box, and tightened the intake boot to the MAF. I got these codes after driving my 2004 BMW X3 3.0i through some crazy muddy logging roads, puddles, mud. Can’t seem to get the codes to trip now. Definitely going to check the connection to the oil separator, I think mines broken. Have a shaky engine upon startup, and 700ish RPM at idle. Cleaned oil from underneath the oil separator today and didn’t even realize that could be the issue. Thanks for the video, seriously.
excellent video. I didn't have a code come up but my 04 325xi was running like garbage and eventually died. just before it started to die out it was making a clunking noise when the rpms would bounce low. my culprit was oil separator return to oil dipstick hose.it was broken in half and dripping oil which also explains my oil consumption. $23 at the dealer. I also changed intake boots as they were cracked almost all of the way through the ribs. thanks again. my car is running better than when I bought it. idle is holding steady
nice video! i have been chasing a grimlin for some time, all new vacum lines and intake manifold gasket, i have yet to re seal disa!! that will be my next step.
Austin Schell I had that issue and I found out a vacuum hose wasn’t plugged in behind the intake manifold and I had a crack in the actual intake manifold so I fixed it with jb weld and fixed issue
dudethank you. you explain everything real easy for me to understand.I'm old school with cars and all this fuel injection stuff is all new to me.I never really understood it till now. I changed all my vacuum lines and shes running great!!!If you ever come out east to the Hamptons, look me up
I think this is the most informative and very clear video especially the way he talks it is very clear word by word its really amazing diction, why can't all americans talk like this guy, black americans its hard to understand their english, i'm an asian american but, i hardly understand black americans. english is not my mother tongue but i can say my english is clear. Anyways, i enjoyed watching videos of this guy, i'm learning a lot when it comes to DIY solving car problems from diagnosing the car and fixing the car issues. Thanks my friend continue to create more videos, you are a 5 star guy.
Fantastic! This is clear, intelligent, and very helpful in understanding the engine, and finding possible vacuum leak points around the engine. Thank you for you effort here.
thanks to your video i found a vacuum leak on my 2000 328CI car run's great now and it's started to get better fuel mileage and I have learned to do more work on my own car saving a ton of "dinero" you know "much mula" and that's great
youre videos have been so much help in my quest to get rid of my power loss rough idle issues. Thank you so much for taking the time to help and share your knowledge.
Thank You! I have already replaced a few parts that have helped in various ways (MAF, purge valve sensor, thermostat, spark plugs, the list goes on), but my main issue is still not fixed. I will be checking these parts. I was told to check them, but didn't know exactly what to check. I will be pricing all of these parts before I even go check, because I'm fairly certain you have given me the answer I have been looking for!
Awesome video. Very informative without getting bogged down in the details. You may have just saved me a ton of money. Half a millions views -- this vid has probably saved millions of dollars in needless repairs. Great job man. Subbed.
An easier check for a leak in the crank case breather valve is to remove the oil cap while it’s running and if there is suction when covering with the palm of your hand, then the ccv has a leak. Buy the whole kit with the 4 hoses, guarantee they are all rotted and will break. Don’t bother doing one at a time and being cheap, it will screw you in the long run. Might as well just get all the gaskets and replace the intake ducting too, from filter to throttle body and get the disa valve gasket too, it’s leaking almost guaranteed.
wow this is the most solid video I've ever seen! I was just searching cleaning maf but this covers alot of good stuff. thanks for the clear explanations and nice video quality. nice to be able to see everything youre doing without shakes or dark spots.
Get video - thank you - really appreciate. Big crack in the lower intake boot and the DISA gasket looks sketchy. On our 330ci, removing the electrical connector from the DISA unit requires unlatching metal clip connector from the motor side of the connector.
A mechanic wrapped electrical tape a few times to ‘repair’ some cracks temporarily on the pipe after the MAF. It worked for about 3 years. Just in case some want a quick fix/bodge!
Thanks for an excellent and concise vid. I was able to detect the cause of my vacuum leak on my 2005 BMW Z4 2.5i thanks to you. I bought the whole kit and had everything replaced by an independent BMW guy.
You are one of the finest teachers I have come across and I used to be one. Such clarity of logic and sequence of causation is a gift. With greatest appreciation, please keep this ability going strong!
thank you very much for the compliment, I will.
I agree completely. Very crisp and definitive, logical flow to all.
Thanks! It cost me 20.00 to fix my leak following your method, the stealership wanted $140.00 just to look at it.
I was about to say the same thing lol
Lol at stearlership 😂😂😂

UA-cam should have invented a DONATE button on every video. Why is this not done yet? Why would you not donate a buck or two for a good video that helped you? Some videos make money by views but most usefull videos don't get that many views but are gold to those who need it.
i know you wrote this 3 years ago but this guy has saved people thousands in labor costs and giving even 5 bucks would make his day and wont effect youre life much at all... i do agree there should be donate button on every video because most useful ones are not getting much views unless people need to find out "how to" something
yes agree it wouldn’t be greedy i personally feel the need to atleast shoot a couple bucks
Sorry to be so offtopic but does any of you know of a tool to log back into an Instagram account?

Man I'm a mechanic myself and your videos have helped me so much with my car. Thank you very much for your time of making them. A lot of people including myself are new to BMW's and you help ALOT man.
I just started throwing a P0174 too. Smoke test was good, MAF was clean, recently rebuilt my DISA. All the usual stuff was good. Turned out to be the air pump control valve and gasket. So keep that in your diagnostic arsenal for future reference. And it's an easy fix/replacement too (beside the exhaust manifold near the front).
You are Hands Down The Best instructor Ive seen in years -
You make trust worthy eye contact somehow and you can easily sense you know your shit.
The way you describe or note any relevant details, tips or cautions with detailed why's are very much needed to create a solid longterm memory.
You should instruct in tech college or an automotive school. One that pays what you are worth.
Video and sound guy ~excellent job as well.
TY for Being and Doing.
thanks so much man!
@@50sKid hey man thanks for the video. Hearing a sucking noise from around the intake manifold. Not sure if it is normal but. Would a bad disa ring cause this?
exactly what i was going to say
Excellent video. For the other 5% of cases, there are also three less common o-ring failures you might want to check before buying a new MAF: Dipstick tube upper o-rings (x2), fuel injector lower o-rings (x6), air distribution piece o-rings (x6).
Also, if you have a 330 then you have a vacuum actuated exhaust. This is a 3.5 mm line that runs down from the back of the intake manifold to a vacuum canister and through the firewall to the rear of the car.
There is also the throttle body gasket and idle control valve grommet, which may leak if reused and not seated properly, respectively.
Finally, if your lean codes are set at highway speeds rather than idle then it is more likely to be a soft failing MAF than a vacuum leak.
clabcon Interesting. The dipstick tube O-rings you refer to are on the dipstick itself, rather than the tube it goes into, correct?
50sKid Yes, the dipstick upper o-rings are on the dipstick rather than the guide tube. There are two of them measuring 9 x 2.22, which is smaller than the lower o-ring that goes around the dipstick guide tube and sump. My upper o-rings were not leaking, but looked worn and flat compared to the plusher new ones and offered greater resistance to removing the dipstick from the guide tube i.e. a better seal. Obviously if you do not check your oil weekly like me, then your upper o-rings will be less worn. It is always good practise to replace the lower o-ring when pulling the dipstick guide tube. For proper installation, lubricate the new o-ring and put on the dipstick guide tube. I have heard they can easily tear and give you a vacuum leak if you put them on the sump and force the guide tube into place. Tolerances are tight so it may take you 30 mins of wiggling to properly seat the new o-ring even when lubricated.
clabcon Yeah pulling that dipstick weekly'll sure do it! Mine sticks in that tube like an SOB and I gotta pull hard on it. I've got about 170k miles on my car and the dipstick tube o-ring was in quite good shape--I replaced it in my CCV videos that I recently did "just cuz," but it honestly was just fine. I think it all depends on if you've gone and left the o-ring in the pan and tried to shove your dipstick tube in that way. But, to anyone reading these comments, Harbor Freight sells a pack of Metric o-rings for $5 and it has the proper size.
50sKid Almost 120k miles here and I have the revised design single walled dipstick guide tube. The damb dipstick snags on a ridge in the bottom and has to be rotated 180 degrees to remove! I think the second batch of these was made in China instead of Germany...
" if you have a 330 then you have a vacuum actuated exhaust. This is a 3.5 mm line that runs down from the back of the intake manifold to a vacuum canister and through the firewall to the rear of the car."
Ah, interesting - the pipe is well cracked on the end of my one where it connects to the exhaust. Suppose it's worth me cutting that off a bit and getting a better seal (or just popping a screw in it, etc - my exhaust butterfly is completely seized so it's not doing anything) before I start tearing the engine bay apart....
This video helped me find a vacuum leak in the E39 that I'm restoring. I'm now also taking proactive maintenance to prevent further issues. Thank you!
What symptoms was your engine showing? Mine varies RPM while driving a steady 65km/h (40 mph). Is this the problem with my engine?
Your Character!... Your compassion, Your love, your crystal voice simply made you one of the best coaches around... You are a born giver... keep up the good work and may God bless....
LOL, thanks very much.
I know this video is 9 years old and it’s been a savior for my ongoing problem. Finally I found the issue with my E39. Thank you for your help and reasoning.
Picked up my first BMW a week ago... Totally different from my old Pontiacs and Jeep's. Found more problems than I expected, getting better thanks to your videos. Great job appreciate em.
After watching numerous youtube video's of a similar issue, this is the most informative & clear. Really helpful & thanks for sharing.
Agree! I have a similar video on my channel but 50skid is a real pro!
My go to UA-camr for anything on my 325i👌🏻
He really is. I always look for him first.
Is there a trick to getting the bottom hose off, both clamps are kinda blocked and there’s a rip in it, or do I gotta remove that brick looking piece in the way?
You make some of the most well thought out, complete, and understandable how-to car repair videos on UA-cam. I will use this later to diagnose the codes on my '05 325i. Thank you.
Dude, you're a hero. I've owned my 325Ci for 7 years, and you've helped me through a lot of jobs. Just had these codes pop up in the last month and need to have a look around. Hopefully it's one of the easier problems to fix, I've put off the CCV for so long. 145,550 miles probably on the original CCV!
I love how you clearly explain things big plusss.... Deff subscribing
I just Donated 50 CENTS to this Video...JUST BY WATCHING IT...GREAT VIDEO..GREAT GUY...very Educated Video for BMW owners ....
seriously dude.... I wanna ship you a fucking 12 pack. My BMW has been running like shit for years... So much so I was gonna sell it... I fixed everything.... MAF, all the hoses, all the boots, the Disa.... Never knew about the oil separator hose... You made my car start back up like normal, after 2 hours of trying to get the damn stupid ass BMW connector off, hate those black squeeze ones... EFFIN A++++++.
Thanks!
I'm in the exact same boat at the minute, going to check those plastic hoses when I get a minute.
50sKid hi have a 318i e46 with p0171 code. it's a m43 engine and im located in France and it gives "problems de transmission du carburant". I need help
I have a feeling this is going to be me
i'm a new owner of 325i e46 from indonesia, i found your videos and this one is my fav. i have no experience about the engine, but you makes me confident to fix my own car. The most important, I'm not good in English but I can understand what you said even without subtitles. Thank you, brother.
Super underrated videos mate! Your CCV one was great, this one too!
My P0171 and P0174 problem was a DISA unit. I replaced DISA and checked every things else as your video. The car is running so far so good. Thanks!
Thank you for your much appreciated time and effort in producing these videos. I'm that personality type that needs to know how things function to fully understand the purpose and vice versa. Simple questions and answers don't quite cut it for me, as there's always a "why?". Needless to say, your videos have helped me immensely! Funny thing is I'm around guys who know a whole hell of a lot more about cars than I ever will and half the time they can't help me for crap!
Thanks a lot for this video. I had just got out of the hospital when my grandsons 2001 325xi started giving him p0171/p0174 codes. I took all the hoses I could get to off and looked for vacuum leaks. I had even taken the intake runner out to get better access to look for other leaks! Didn't know enough to look at the gasket at the time. I only knew that when I sprayed brake fluid into the general area of the intake, I could occasionally get the engine to go rich for a while. It was so tight an area that it was hard to locate exactly where the spray was impacting the leak. I almost gave up and had the car taken to a shop to be smoked when I ran across your video. One viewing of your video and I knew it was the seal on the intake runner. Borrowed an incorrect sized seal from my neighbor and managed to prove it was leaking(couldn't quite get the intake runner shoved back into it's slot-but the seal held). Have ordered a new seal and will be in next week. In any case, your video was instrumental in my fixing his car. BTW, I too broke a rubber housing taking it apart(ironically, BMW had that housing in stock for $22 but wanted $400 for the intake runner because they didn't sell the seal by itself! Thanks again!
The dreaded codes for all BMW owners. Solid video, thanks for sharing your experience with identifying the sources of leaks.
Looking forward to more of your BMW videos!
You are the MAN!, thanks for your videos 50's kid. Add a donation link to your youtube page, you deserve some rewards for your good advice!!! i had this issue for years, sent my car to mechanics and kept changing sensors, and i gave up, until i saw your video. I followed steps by steps and got it fixed. I am not mechanic but you made it so easy, anybody can do it. I had vacuum leak on top air boot, my disa also was leaking and the bottom boot was also fixed with electrical tape!!!, i fix these 3 f(including the cabin filter) or less than 50 bucks!!!. Thank you for being around, we E46 fanatics will appreciate it.
This was excellent dude, thank you! Such a good explanation of the M54 vacuum system. For anyone wondering, this information also applies to 2004-2006 BMW X3 E83.
Just went through my E46 to fix a vacuum leak and update the ignition system at 141000 miles. After replacing the valve cover gasket, DISA valve, fuel injectors, and several vacuum hoses I still had a rough idle. I finally broke down and replaced the lower hose on the CCV and O-ring on the oil dipstick tube to finally get the vacuum leak fixed. Thanks for pointing out those parts as failure points. Maybe I should have started there first!
great video. One thing you can do to find leaks faster is to attach a glove on the intake boot and attach a hose to the glove. Then i used an electronic cigarette to blow some smoke through the hose i attached to the glove and i found my lower boot and the disa o ring was leaking.
This might be a stupid ? , do you do this with the car on, just idling or with the car off?
Car off!!!
Please do a video!
Crazy! I just did this the other day. Only thing I did different was I took the f connector off, stuck a straw in the intake boot, and started puffin
Hi 50s kid .. buying this 2004 3.25i for my kid has been quite an experience. going from GM to BMW was like swiching from APple to Anroid!! Here's an idea that worked for us to put the car in great condition .. you've never mentioned a smoke test .. but it sometimes would make sense. But I didn't want to do that because I thought of a simiar test .. I bough some 16 inch punk sticks. They are meant to make your house smell good .. but they generate a lot of smoke. I started the engine then moved the punk stick nes possible leak areas. In my case it was the Oil cap leaking. No doubt why it was leaking .. The ccv diaphragm was ripped before I bought it. With your video it was easy to find and fix .. but it must have been that way a long time because the oil cap gasket had a GIANT depression from being sucked in all the time. Thank you so much for the videos.
Great video! I suspected a vacuum leak but it ended up being a completely failed DISA valve (O-ring was fine) on my 2004 330xi. Replacing that should fix my P0171 and P0174 codes along with random misfires. This video saved me a lot of time. Thank you for taking the time to make this video! Keep up the good work!
Did replacing the DISA valve fix your problem? Im about to replace mines
Bro 5 years later your video is a life saver. I bought a wild shit project, tell me how I just went out and everything you just pointed out leaks.....
Having some difficulty with my e46 with a rough and weird idle. I diagnosed it and it came back as these codes. Im having a tough time finding the leak.
What did you end up doing to it
Having the same issue rn
This guy is Legend.
53 dislikes? really? probably all from disgruntled stealerships, the game is to be told not sold.
Appreciate the support. It just comes with the territory, someone is always going to click dislike. ;-)
I have been a victim of all of the more common faults. You have been my go to instructor, before I open anything. I wish you a long life, don't want to be out here alone.
Thanks!
You easily saved me over $1000.00 at a dealership. Big thank you for this video! If you ever come to Sacramento I'd be more than happy to buy you a beer. Thanks again!
My 2002 330i was having an extremely rough idle and sometimes having problems accelerating like it had no power. The engine would even cut out randomly when I was at a stop light. The problem turned out to be my MAF Flap adjuster unit, the flap was snapped off and floating inside the unit. 20 minutes of labor and $150.00 part and my check engine light is gone and my car runs like new!
Nice, glad to hear!
I got the same problem
Many thanks, brother... I knew my E36, inside and out. Bought an '01 E46 325xi, and the M54 engine bay has me stumped at times. I want an original Owner's Manual, and the Bentley repair manual, but your videos have been SO HELPFUL
I fixed one vac leak and made another huge one several weeks ago. Had a bad vacuum leak at the DISA valve, replaced the molded gasket with German Auto Solutions o-ring. Started the car up and it ran about 5x worse than it was. Turned out I roughed up my original upper intake boot up a bit and had a 3.5 inch split in the bottom of it. Got a new upper boot and lower one even though it was replaced 5 years ago and now it runs beautifully with no codes. I had 7 total with the P0171 & P0174 and various cylinder misfires.
+tyler951 Nice job.
Had P0171 and 174 for the last 6 months... engine just started to idle horribly and starts to die if I don't let it idle until warm (while pushing the throttle above 1k RPMs because it's sitting around 500 RPM shoddily otherwise).
Replacing the DISA, ICV, and intake boot tomorrow using your videos. Thanks so much for such quality material.
Dude you have officially made it to the top 5 people I’m going to for engine specifics! You are so knowledgeable! Thank you for the video!
Had a vehicle come into my shop with all the same issues, I replaced the DIsa valve, replace the crankcase hoses and pvc system also, the intake hose. The intake hose had its common leak, I replaced that. I then found the crankcase problems tube to the dipstick was broken, still had a problem, I then smoked the intake with a smoke machine no leaks found. After looking and looking I narrowed it down to the brake booster which had an internal leak. I tested it by unplugging it and the capping it off idle remained normal, no codes. Now I need to learn more about the VANOS repair, your videos are very informative and thank you!
+Rick Singh Very nice, thanks for the info about the brake booster!
+50sKid - thanks budddy, do you have any info or videos that I can look at to diagnose the Vanos on these vehicle's, it seems like I am running into alot of failures on bmw's. Again, I appreciate your time and effor in putting these videos up, its greatly appreciated.
Rick Singh Well I'm not entirely sure which are the common codes that basically mean you have to rebuild the VANOS, but this guy has a good video on the procedure: ua-cam.com/video/IBJL9AkS6Qc/v-deo.html -- I've also heard of the two solenoids on either side getting stuck and needing to be cleaned out, and those problems resulted in different codes being set (again I don't remember which ones, I'll have to make a note for my future video). What codes are you seeing?
+50sKid - I will update you when I run into another problem with one. I don't remember the codes top of my head I do get a lot of these cars for repair these days. I have my own private shop that I run, and these cars are very tricky at times to diagnose, thanks again buddy.
+Rick Singh Excellent, keep me posted on the VANOS stuff.
Thank you so much for your detailed explanation. I am a female and don't know much on car repair. Your a godsend. Great job.
50s Kid- you rock! You helped me a lot by doing this video, since I learned where to look to fix a big vacuum leak(s). I just got done replacing my DISA valve and also repaired a crack in the lower boot (just used electric tape around the crack so I wouldn't have to wait to get a replacement boot). Car runs great now.
this man will make you way more confident in trying do the work yourself and be comfortable doing so knowing you have got the best instruction to tackle any job. thanks bro
I have a major problem with this video.. your clarity and explanation gives me the confidence that I can do this.. I just want to say thank you for this video. I had the maf cleaned, plugs tightened filters replaced or cleaned my car runs great it makes a sound that I don't like when I turn the car off.. Codes wont clear, time to check for vacuum leak.
+Bart Pack Thanks!
Hoollllyyy smokes. This was the explanation i needed. In all honesty, this is making the fault deduction process way easier when its explained this way. The mechanics of how these systems operate. I just replaced my alternator and had to remove the air flow system to get to it, (sounded scarier than it axtually was) and aftet i placed everyhting back together, these 2 codes popped up the next day. 2 days after when i had time, i re-removed the air flow system again to make sure EVERYTHING was tightened back correctly, (and replaced my air box filter in the process) then the code dissapeared right after. Fast forward 5 days later, codes are back. So at least i know what im lookin at now after this videos details. TYSM 😊
I've used a number of your videos to help me out several times. Very clear explanation, very matter-of-fact, very informative. Thank you. I discovered a sneaky air leak... When rebuilding my DISA valve I noticed that the seal on the actuator arm was badly damaged. This is easy to overlook and is not included in the repair kit and leaks a lot of air. I purchased a standard oil seal 22mm dia, 12mm shaft, 6mm thick to fix this.
50's kid- you are the best! Its great that I am able to back to this video after four years to get a refresher. Love my '05 330xi- had it since new. Now i just have to figure out whats causing the odd rattling sound coming out of the exhaust pipes on cold starts. not too worried cuz it goes awy when it warms up.... but....
I kept getting those codes and I kept resetting them with my bluetooth scanner. I knew that it was some sort of vac leak due to the fact I would hear a whistle sound under acceleration. Now that I have time; I will be addressing these issues. Great informative video!
this man makes the best videos because he teaches you the knowledge you need to diagnose the problem yourself the as best as possible without a professional
Here's my story and it has a happy ending. About a half mile from home my 2003 530i engine started running really bad. No power, coughing and backfiring. Of course the check engine light came on and the 1071, 1074 codes where there along with some 1350's miss firings. I followed all the advice in this video and used about 2 big cans of carb cleaner trying to find the air leak. To no avail. 23 months ago the OEM fuel pump just quit. No codes in the computer when it failed. So after trying everything in this video I thought why not check the fuel pressure. I went to Autozone and thru their loan-a tool program got a fuel pressure tester. Instead of 40 to 45 psi of fuel pressure I had only 15 to 20 psi. Just enough to start the engine but nothing more. So unlike the last time where the pump completely failed this pump was still putting out some pressure. And the replacement pump had a 24 month warranty so I got a new one for free. So my point is after trying everything in this video, if there is still a problem check the fuel pressure.
You are the man! Did a temporary fix to one of the hoses until I get a replacement for it. Never thought some of them would get brittle like that. This video is very helpful! Thanks again!
Thank you after taking my 2004 530i to a crooked repair shop for an oil and transmission service they proceeded to tell me .Have a bad switch on my transmission $$154 part $4200 to fix..Small oil leak they wanted $2200 to re-seal my oil pan.. Unbelievable.So they refused to change the tranny fluid charged me $125 for checking ..And faulty I-drive to check $125 allegedly did a reset pressed 2 buttons...After doing an oil change Ac/recharge wheel alignment and installing 4 tires I bought.. Charged me $809 no lights were on in my car 1 day after driving Service engine light soon comes on ..I refuse to bring my car back to these crooks..Service engine codes read these same codes you speak about. I bought a code reader off Amazon and cleared them...I will check for some of the symptoms you showed ...Thank you
your videos are amazing. they have helped me bring an 323ci back from the dead. from check engine issues to trans issues and fluid filling. thanks again
Mate , Fair dinkum you could talk a bloke off a high ledge, a very articulate & effective explanation of air leaks on these M54 Z4 shitboxs has saved my arse big time down in Oz.
you’re a deadset legend .. cheers 🍺
I have these codes now and my valve cover just started leaking. I will have the gasket replaced on those, hopefully it will fix the issue but will still inspect for other culprit for vacuum leaks you mentioned here. Very informative. Keep it up!
Hey 50's kid. I'm also a 50's kid with a recently acquired 2002 E46 330Ci Cpe. You produce awesome videos, and I've learned a LOT. The car is throwing a P2096 Post Catalytic Fuel Trim System Too Lean Bank 1 error, so I cannot get it smoged. I'm a mechanical engineer, but alas I don't have the time to DIY. I'm looking for someone like you in the San Fernando Valley who is proficient on BMW's; namely upgrading DME firmware and diagnosing vacuum leaks? I took the car into an indy repair shop and they quoted me a ridiculous $1,300 to do what I consider a costly trial by error fix; replace the two post cat O2 sensors ($500) and the ICV ($350) + labor ($450). From my understanding, the sensors cost ~$80 each and the ICV can be cleaned. The car has a K&N intake filter, and on inspection the post MAF intake boots are clean, soft, and pliable, but that's as far as I went. Can you provide a referral?
+David Rosenthal Check to make sure the O2 sensors are tightened fully. When I was getting a P2098 error (bank 2), it ended up being that the #2 pre cat oxygen sensor was slightly loose and causing a vacuum leak. I can't make a referral because I do my own work. :-)
+50sKid, If you had a shop, I'd be a customer.
By far the best, most informative bmw videos I've viewed on youtube. Has help me immensely repairing vacuum leaks on my e39 m52tu.
I replaced my ccv valve and all hoses associated with it about 2 years ago after having burning oil issues, but now the car runs much better. However I did not buy all the right gaskets. I have p0171 and p0174 popping up. I have a hissing leak coming from the intake manifold gasket I believe and I will have to replace it. I could be wrong because It is important to replace and check so many things while doing this I realize, now I will have to tear it all apart again, just hoping I don't break something else! Patience is key thank you for your video.
The intake gasket usually is not a problem.
You explained everything so nice, I’ve had a issue where a plugged in MAF sensor makes car run rough and die after a while with a EVAP Large Leak, yesterday before this video I did a smoke test and found a leak by that little hose near the throttle body, fixed and still same code and it’s driving me nuts after I’ve replaced 75% of the items you’ve said. You did mention some other that I haven’t checked that I will definitely be checking now like the o ring on the oil stick!
First of all, thanks for running more than excellent channel. On my euro spec (no aux air pump) e46 330ci, I had a whistling sound under partial load and occasional lean codes. I have since replaced my CCV, intake and throttle gaskets, intake hoses, checked the ICV and pligged ports, checked the brake booster line amd check valve, EVAP lines etc. Disa O-ring is tight. I smoke tested it with a glove over the MAF (which I also cleaned out with the designated spray) and it seemed al right, the nitrile glove even remained inflated. Still, I can hear a whistle under partial throttle/load and it will occasionally throw a lean code (both banks). Vanos was overhauled/resealed and valve cover gasket replaced at the same time. Oh, and both O2 sensors are new. I'm out of ideas, please chime in if you could. FPR vacuum lines maybe?
A big thanks for your video here and the one about how to remove a bunch of key components. You guidance helped me diagnose the massive air leak in my lower air intake boot and another minor hose issue. Couldn't have done it without you. Thanks!
Nice, good going.
Many thanks for a very useful video. My 1999 Z3 2.3 was throwing "O2 sensor adaption limit" codes (as per my Peake R5 FCX3 scan tool). Using this video I was able to quickly isolate the problem as a hole in the lower intake boot which was creating a colossal vacuum leak. I replaced all of the intake boot parts, cleared the codes, and all is now well.
Let me just say Thank You, You are a great help! Keep the camera rolling and your mind speaking. BMW owner in Alabama...
+Paul Zapata Will do, thank you!
You have the best e46 repair videos. Thank you for what you do, man. i just got a 04 325ci that sounds like a vacuum cleaner sucking air, on start up. The guy I got it from, lacks the mental faculties to diagnose an untied shoe string. lol. So, I'm going to go through the entire car. These vids will help out greatly!
You are incredible, Kid.
Your videos and explanation detail is the best I've seen. I've taken my BMW X3
to the dealer 2 times with this same issue. Lean fuel PO171 & PO174. Still
coming back like a nightmare. They said they did a
smoke test, checked normal. First time my air filter was changed and gas manual
something was changed. Second time they changed the fuel filter. I lost my
faith with the dealer, looking to take to a good mechanic not, like. Hendricks
BMW likes to fix one problem at a time.I bought a scanner now to
help me diagnose and primarily remove the annoying service engine soon light.
The concern I have now is the MAF sensor. I unplugged it
and engine did not stall, like I expected. Is that a good way to test? it cause,
I cleaned it, reset the light and after 400 miles its come back.You are incredible, Kid. Your videos and
explanation detail is the best I've seen. I've taken my BMW X3 to the dealer 2
times with this same issue. Lean fuel PO171 & PO174. Still coming back like
a nightmare. They said they did a smoke
test, checked normal. First time my air filter was changed and gas manual
something was changed. Second time they changed the fuel filter. I lost my
faith with the dealer, looking to take to a good mechanic. I bought a scanner now to help
me diagnose and primarily remove the annoying service engine soon light.The concern I have now is the MAF sensor. I unplugged it and engine did not
stall, like I expected. Is that a good way to test it cause, I cleaned it,
reset the light and after 400 miles its came back.You are increasable, Kid. Your videos and explanation detail is the best
I've seem. I've taken my BMW X3 to the dealer 2 times with this same issue.

Your car isn't supposed to stall when you unplug the MAF, it just stumbles and recovers. That is normal. I don't believe that they did a smoke test and found nothing wrong.
50sKid when I unplug MAF it didn't do any on dash gear light came on. Nothing else runs fine.
Also it's a 2005 X3 3.0i if it makes any difference.
Also Kid the connection between the exhaust manifold and the muffler junction. After watching your videos and performing the repairs I was still having a code but this time for some unexplained reason a P0174 code showed up. So I heard you talk about leaks around that area that can cause a problem and sure it did carnal ... the other two Ox sensors are located close to the exhaust leak causin the pitot effect drawing more air than registered. Took it to the muffler shop and eventually that took care of the problem.. Thanks Kid , Thanks for sharing your knowledge Base with us... Keep your channels running. And enjoy your weekend
+Sumbamotor1 Nice work!
Excellent information. I have owned my 2002 BMW 325csi since new, and am having the vacuum fault code occur regularly, and now a rough firing engine, with the fault code on my OBD reader indicating this problem. This is excellent information for me, and as I am a long time hobby mechanic, I will check out all the potential sources of the cause. Thanks again... ... Fortunately, my 1966 Lotus Elan does not have these type of problems.... Dual Web Carbs and "O" rings on the intake manifold are all that I have to check.... oh well !!!!
After watching this video and reading the comments i went back outside and pulled the secondary check valve out and inspected the little gasket and noticed it wasnt sitting on one of the two 10mm studs and was only sitting on just 1 smh SOOOO obviously it wasnt seated properly and i could actually see the soot on the gasket where it was escaping. Hopeing now that this is sealed off maybe now the lean codes will vanish. I have the legendary p171 p174 and also p 430....😮😮😮iam in such shock that iam afraid to go back outside and start her up...i cant believe the gasketbwas on wrong n a healthy amont of carbon on the gasket shows exactly where it was leaving...that has tobbe enough especially especially at 2500 rpms...🎉🎉🎉look at me i cant shutup!!!! ....all thanx to this video!!! 50zzz KID😊😊
great vid just fixed my buddys e46, found the oil drain tube at the dipstick was cracked causing lean codes, cleared codes and no more problems thank you again!
Thank you, great video! I had both codes P0171 and P0174 for a few weeks now and finally found the reason to be number 3 on your video. Breather hose coming from oil separator/CCV to oil dipstick looked like it was trampled... Changed it and after that no fault codes referring to air leaks.
This is one of the best vids on this issue bar none. I can tell you are a software developer for sure! Thank you very much for helping us all. Jimbo
Best channel for e46 owner's ever!!
Had the codes. Lower intake elbow damaged. Thanks for the tutorial great work!! Your oil change video helped me loads as well. Annnnnnd your instruction on diagnosing a misfire and replacing spark plugs! Great videos.
Such a fantastic breakdown homie. Concise, organized, and well-spoken. Thank ya !
Thanks a Million my friend you helped me understand more than I knew about the Vac Sys. Because of you papa I got to understand my Car more. Following your Tutorials I have managed to trouble shoot my car step by step and fixed all of the glitches I had on my Vac Sys.. THANKS AGAIN.. If you were closer we go for some Beer... Thanks again You are a sanity saver..
+Sumbamotor1 Nice, great going!
This video is amazing, thanks for all the valuable info. I deep cleaned my air filter, air box, and tightened the intake boot to the MAF. I got these codes after driving my 2004 BMW X3 3.0i through some crazy muddy logging roads, puddles, mud. Can’t seem to get the codes to trip now. Definitely going to check the connection to the oil separator, I think mines broken. Have a shaky engine upon startup, and 700ish RPM at idle. Cleaned oil from underneath the oil separator today and didn’t even realize that could be the issue. Thanks for the video, seriously.
excellent video. I didn't have a code come up but my 04 325xi was running like garbage and eventually died. just before it started to die out it was making a clunking noise when the rpms would bounce low. my culprit was oil separator return to oil dipstick hose.it was broken in half and dripping oil which also explains my oil consumption. $23 at the dealer. I also changed intake boots as they were cracked almost all of the way through the ribs. thanks again. my car is running better than when I bought it. idle is holding steady
nice video! i have been chasing a grimlin for some time, all new vacum lines and intake manifold gasket, i have yet to re seal disa!! that will be my next step.
Austin Schell I had that issue and I found out a vacuum hose wasn’t plugged in behind the intake manifold and I had a crack in the actual intake manifold so I fixed it with jb weld and fixed issue
dudethank you. you explain everything real easy for me to understand.I'm old school with cars and all this fuel injection stuff is all new to me.I never really understood it till now. I changed all my vacuum lines and shes running great!!!If you ever come out east to the Hamptons, look me up
Thanks!
I think this is the most informative and very clear video especially the way he talks it is very clear word by word its really amazing diction, why can't all americans talk like this guy, black americans its hard to understand their english, i'm an asian american but, i hardly understand black americans. english is not my mother tongue but i can say my english is clear. Anyways, i enjoyed watching videos of this guy, i'm learning a lot when it comes to DIY solving car problems from diagnosing the car and fixing the car issues. Thanks my friend continue to create more videos, you are a 5 star guy.
Your video really is a eye opener on things to know about these engines so I appreciate your time with your food for the brain on e46 motor, thank you
Fantastic! This is clear, intelligent, and very helpful in understanding the engine, and finding possible vacuum leak points around the engine. Thank you for you effort here.
This information is right on spot, This guy knows his stuff
thanks to your video i found a vacuum leak on my 2000 328CI car run's great now and it's started to get better fuel mileage and I have learned to do more work on my own car saving a ton of "dinero" you know "much mula" and that's great
+Armando Pérez Excellent!
youre videos have been so much help in my quest to get rid of my power loss rough idle issues. Thank you so much for taking the time to help and share your knowledge.
As a e46 and e39 owner I love u and Nathan
Thank You! I have already replaced a few parts that have helped in various ways (MAF, purge valve sensor, thermostat, spark plugs, the list goes on), but my main issue is still not fixed. I will be checking these parts. I was told to check them, but didn't know exactly what to check. I will be pricing all of these parts before I even go check, because I'm fairly certain you have given me the answer I have been looking for!
Very resourceful video. I have both of these codes on my e46 and now I am confident I can do this repair myself now.
Awesome video. Very informative without getting bogged down in the details. You may have just saved me a ton of money. Half a millions views -- this vid has probably saved millions of dollars in needless repairs. Great job man. Subbed.
An easier check for a leak in the crank case breather valve is to remove the oil cap while it’s running and if there is suction when covering with the palm of your hand, then the ccv has a leak. Buy the whole kit with the 4 hoses, guarantee they are all rotted and will break. Don’t bother doing one at a time and being cheap, it will screw you in the long run. Might as well just get all the gaskets and replace the intake ducting too, from filter to throttle body and get the disa valve gasket too, it’s leaking almost guaranteed.
wow this is the most solid video I've ever seen! I was just searching cleaning maf but this covers alot of good stuff. thanks for the clear explanations and nice video quality. nice to be able to see everything youre doing without shakes or dark spots.
+Aaron Hunt thanks, bro
you are very thorough with your explanation of everything. Thank you.
i like this guy he know how to break it down in a easy understanding. other videos not so great but this guys pretty amazing
HATS OFF TO YOU...THE BEST VIDEO IVE EVER WATCHED ON UA-cam...
Thanks to you I found the intake boot was torn at the places you said. Replaced it. So far so good. Thanks
Get video - thank you - really appreciate. Big crack in the lower intake boot and the DISA gasket looks sketchy.
On our 330ci, removing the electrical connector from the DISA unit requires unlatching metal clip connector from the motor side of the connector.
Excellent - wish I had this handy about five years ago...when I stumbled through just these areas! Well done, and fine explanations
dude, your videos are amazing! you've helped me so much throughout this e46 journey so much! keep it up man! you awesome!
A mechanic wrapped electrical tape a few times to ‘repair’ some cracks temporarily on the pipe after the MAF. It worked for about 3 years. Just in case some want a quick fix/bodge!
Thanks for an excellent and concise vid. I was able to detect the cause of my vacuum leak on my 2005 BMW Z4 2.5i thanks to you. I bought the whole kit and had everything replaced by an independent BMW guy.
CONGRATS ON YOUR SILVER PLAQUE WE HOPE YOU COME BACK!
