I just respect this guy for saying it the way it is, “don’t think you have a special car, there is nothing special about it or you.”
Great video.
Always nice to see helpful tips from someone who knows those engines!
Glad it was helpful!
I sure as hell enjoyed the video!! You reminded me I’ve got to convince my Mrs. to do the damn update finally ! Thanks for all that good info dean!
no problem my friend let me know when your ready my friend
Great vid as usual mate. Just one thing with the MAF - there IS an issue with these silver top motors (analogue MAF) where the plug can cause connection issues with the MAF itself. It presents itself as a 2d06 or something similar. I had the issue on my N52 (130i). Simply cleaning the MAF, it's terminals and the plug terminals with MAF cleaner and electrical contact cleaner worked for me, but some people need to replace the plug plastic and pins. Very cheap parts, but soldering required. Just thought I'd mention that!
Straight to the point, do not use " the cheap parts"!!!!!
exactly that and I will keep saying that on every video till people get the message
Some things are cheap for a reason
@@BMWDoctor how can I get the update for my dme for the n52
Really helpful video, thanks Dean.
This is great! I pulled the manifold to replace the DISA valves and the map sensor wire was broken and the mechanic used wire nuts and electrical tape to fix the wire!
You're such a life saver, im so glad i found your yt channel.
Well done mate. Really useful.
Thanks, you're great bmw Dr.
Bravo, Dr. N52 aka Dean!
Super!
I have the same n52 do I need to change the manifold to make it go faster.
Great video Dean!
Legend!
Helpful infor keep it brother.
Love this guy
Hello very helpful got plenty to look at on me 125i rough idle ha .thanks!
No problem 👍
Damn dude you went off this video, good shit!
Hi sir,
Is it posdible to change your valvetronic motor and proceed with the battery disconnect reset mode?
Thanks.
Doctor, what is the black box between the intake manifold and air intake box? Can't see that on my N52 with silver value cover built in Munich (E90 2006 325xi)
Doctor, been meaning to ask you this for a while...what is the black box between the intake manifold and air intake? Can't see that on my N52...
How many miles can you usually get on vanos solenoids before they start to give you problems? Thanks!
Vanos sylinoids def gotta be my issue thanks bro. Change high and low pressure fuel pump, water pup had it updated and then I noticed the ruff idle vibration. Gotta be the vanos sylinoids.
Does this also cause shutting off the engine randomly while on a stop or parked? I have a e90 323i
would this apply for my 2015 435i gran coupe?? i replaced my valve cover gasket, spark plugs, and oil at the same time and i’m getting a cylinder 4 misfire code along with a rough idle when i turn it on
Hi bmw doctor
Could you please make a video on how to code apple carplay on a bmw f series please
Thanks great vid
Hi Dean I know you don’t answer questions however my timing chain stretched on n53 engine could soilnoids do this ,the car only done 80000 miles did change the soilnoids to one ones after the chain was changed because I was getting codes just point out though didn’t have the car long now I’m wondering if someone had put cheap parts on the car as I thought timing chains were 100% on these engines .
great thorough video again doctor! I re and re my Valvetronic motor for VCG, didn't relearn the motor with scan tool. Car starts up and drives no problem, but have a little rough idle. Do you think this can be the reason from not have it relearned it's steps? Thanks in advanced
No, it's likely one or a few of the 20 other things he mentioned
Hey BMW Doctor I love your videos! Also, does the DME update apply to US-spec N52’s? I have a 2011 328i xDrive.
Nice video. I still have a small rough idol on cold start. N52k all 6 spark plugs and coil packs were charged at 60k at the dealership.
I appreciate your knowledgeable advice...however...you forgot to mention CHANGE THE DIRTY OIL!.....Also, we have had a hit on income, and it is highly recommended [like u said] to make sure you can afford a BMW....I was an aircraft mechanic and BMW is killing me❤😂...but I have learned a new respect
hi ! many owners have relearned valvtronic with ingition , but very confused now as you said it need to be relearn with scanner, is there really a risk to relearn with ignition ? if you can do a video of relearning valvetronic with scanner it wouls be very helpful thks
My X5 throws misfire codes and the whole air intake is shaking..what you think on that?
Also my 328i has no code but rough idle Nd makes a loud noise like it coming from where the exhaust manifold meets the exhaust pipe
Hi Dean, I'll like your advice on a purchase of a BMW 320i 2015 model doing 80,000 km.? Thanking you in advance and looking forward to a feedback.
Bmw doc I got a question for you can u put z4 cams on a 2006 325i
Previous owner did the valve cover gasket. Not sure if they did the valvecentric re-learn or not. I did DISA valves, new vanos selenoids, cleaned vanos filters. All codes gone car idles a little funny only when AC is on. Yes I used chinese stuff just because It's my 1st BMW and I'm afraid to dump a ton of money not knowing if I made a mistake buying this car. I will replace them with oem once I'm confident. Car is a 06 330i with 220k miles.
You should own bmw u are my man
#bmw
Thank you
You're welcome
How and where are you based in the UK Dean? I’d like to come to you for the software update.
please do you have a similar video on the N62.
Good information
So nice of you
Hey Dean. I have two strange problems with one 128i with N52 engine. When starting hot the car missfires and has bad idle for like 3-4 seconds and after that it runs like a dream. This is every hot start ever. The other is that there is a strange grinding noise coming from the engine compartment. It is definetly not the lifters, I have watched your video. I think it might be the oil filter. When I touch the gas pedal the noise dissapears right away. There are no codes in the DME, I scan with Ista. Thans for your videos !
Hey
Great Video!
I have a rough idle problem with my E64 630i
when cold. The engine code is N53
Would you have any ideas what could be causing this problem .
Thanks
Hi there,
I have a Mini with the B37 diesel engine, and something very weird is happening, so after a few hard accelerations the swirl flap will stuck at about -7% no matter what the desire value is, and the turbo will not work (and the acceleration will become very weak) until the car is restarted, what could this be? Thanks
Hello. I bought a used BMW 523i N52 F10, 2.5. It came with a bad DME, so I went out and bought a DME which was programmed and fitted. I have a Drive train Malfunction and its showing a Misfire after DT. Would you recommend a Software update on the DME??
Can you help me with my 09 x5 with the inline 6 n52 motor ? The oil keep coming out at the back seal even after changing it 4 times
pulling out MAF cable or put back in, dose nothing runs shit on cold still, so the MAF is bad then ?
Would any of these issues cause a missfire only when idling and fully warmed up? My car starts and runs fine initially and also runs fine under load but stutters at idle once warm. Above 1000rpm it is fine. Missfire is across all cylinders and has no obvious pattern to it like it does when a coil goes bad etc.
Omg , now I get the answer from u bro, may God bless you and your family and I pray to God ,may God give good health and happy life to u and your family. Amin....
Awesomeness
How do I go about getting the DME updated?
poocb code low air flo.replace coils and plugs,changed mass flo air sensor.running a little rough when on a cold start.do you know anything about this codes fix.thanks
I bought cheapo vanos solenoids (no name) for my N52 at first because of codes, but still caused issues and threw vanos codes. Went with OE solenoids (4x price) as recommended by Dean and no codes since :> Parts look very similar but seem to perform very differently.
Hella (German brand) cam shaft sensors (made in China) has worked fine on my E46 though. Guess "no name" parts is no-no if expected quality is yes-yes ;)
there you go my friend and i'm glad you took my advise this is why people see me differently. and everyone can say what they want about me but the fact remains you CANNOT I MEAN CANNOT get away with cheap parts on this engine and people hate me because i tell them the truth.
i'm not here to have your cars running like a bag of spanners just to keep you watching and watching to get more views until i decide to put out a video showing your problem LIKE MOST DO !!!
i only tell the truth about these engines and what is required to get the most power best fuel economy and the best sounding and performing engine the way it come out the factory.
MOST UA-camR'S will make you use chinese parts just so they can benefit from the clicks and parts bought to fund there own pockets as many of you realise i'm not like that i don't like up all these parts to make you guys click.
also alot of these guys on here will fit these cheap parts and then replace them with genuine after the video and not even record it and then say there car "is still running perfect" with the chinese part as there PAID to do them videos
Hi mate can u help please I got a bmw 525i m sport 3 litre and its rough idle in cold start after driving it it goes away and the code I have is po175 system too rich bank 2 can u help please thx?
BMW Doctor I have a problem I have a 2011 BMW 328i e-90 engine 52 3.0 L
I'm getting a 2A7C DME cam shift verbally timing. How can fix the problem thank you.
Hi m8 great video i have rough idle just first 15 sec from cold start car runs like dream just rough idle straight after start with a bit blue smoke. What should I look at it. Cheers
Great video bro, I have a 2004 120i e87(n46) I have rough idle, only seems to do it at 750rpm, seems fine to drive though. I have code p110d (throttle position sensor) does this mean I need to change the accelerator postition sensor/accelerator pedal? I can't find a throttle position sensor anywhere. Plugs and ignition coils have been replaced. Thanks man
How do I do the update?
How do you do the same update
Hello, I need help with my BMW e60 M54 error P28A2 P281E
I can't drive the car is shaking
Thanks
I wish I live near by you , so u can fix things...I love my car and I'm in USA...745i..2004
Loving all the N52 content. I have watched several of your videos and they have helped me diagnose and repair a couple of things much quicker than I could have without.
I am curious though... You have mentioned several cars that have this engine... but mine's not one of them... I have a 2007 X3 3.0si (manual) ... and I expect there are a few differences (like DISA) but I don't know what they might all be. Do you have a video or know a good resource to see what the differences are between the different N52 variants?
On a total tangent... Nice as the N52 is, I have a lot more love for the S52 in my E36 M3, and have added pretty much every possible bolt-on available... I don't know of nearly as many horsepower or torque bolt ons that I could (or would) do to an X3 LOL.
Thanks again for all the great content!
My ESS went bad...I replaced it with a genuine ESS...now the car idle is rough? I replaced Coils and plugs, thanos, still same problem?
Does it work for 2007 750Li BMW
is the 525se gearbox cooling rad easy to replace ? 2001
have no idea my friend thats E39
Hey bro nice video!
I have a problem at the moment with my bmw 135i m sport 13 plate
The car was misfiring I brought new all 6 sparks and coils and again still misfiring!
Iv done everything bro and I don’t know what to do I need help!
Do you have a garage?
Kind regards
Any ideas for an intermittent vibration at 80mph? Not correlated to rpm, have had the tires road forced balanced and have new wheels. The vibration is very consistent, it phases in and out. ~3s of smooth driving and then ~5s of shaking increasing and then decaying. this cycle repeats while the car is cruising at 80mph.
Might be a broken reluctor ring on one of the drive shafts, which forces the TC to activate the brakes since it reads a speed difference between the rear wheels.
How much do you charge for the dme update?
How do I get my dme updated I’m in the us
have cleaned my factory vanos solenoids more than once in the 100,000k ive put on my car. and it DOES resolve some idle issues
How much is it for the dme update
It works for the bmw 128i?
My 07 z4 relearned the valvetronic motor. I've done it a few times.
do you mean your z4 relearnedthe valvtronic just with ignition ? i also have a z4 but very confused if it can be done with ignition or diagnose tool absolutely
This aplicated in Bmw X5 with N52?
Mate can you make a video about the E46 318i 2003 engine ? I am having rough idling , scanner showed camshaft sensor , exhaust, ambient temperature, thermal oil-level sensor . I ain't sure what the problem might be but please, if you know or make a video , I would really appreciate it .
Note : we got really bad BMW mechanics in Lebanon, please save my ass brother
Hey Doc, I am throwing a P2096 code and had a rough idle. My mechanic changed both upstream 02 sensors, did a smoke test (no leaks) and there is still a rough idle, almost like the throttle is acting like im giving the car gas. Any ideas?
Sounds like you are running a bit rich, could be leaky injectors if there are no vacuum leaks, or it could be related to the MAP sensor on the intake manifold which influences long term and short term fuel trim
hey I just owned a a BMW 525i but it was park for one year but start some times am from Jamaica but living in Saint Kittsand Nevis now can I get a number for you
I need a Mecanic like you. Where can I find you???
Thanks :
How do i do the update i just joined your channel also a new bmw owner

Hi Dean. I am planning on swapping my standard N52 intake manifold to a 3-stage intake manifold on my 2007 Z4 3.0 I to convert it to a 3.0 SI. Can I run and drive it before I tune the ECM? I know I won't have full power at that time. Also do I have to add on a CCV system for it to work properly? Mine has the y-pipe right now . The new intake came off of a 2006 330i. Thanks.
Bro how do I come with my car to see you
Love it, "don't buy Chinese junk" "if you can't afford to look after it get rid of it now" 👍👍👍🤣🤣
I have a 2010 Z4 that in sport or sport+, ac on high, hot summer day DIES randomly when you come to a stop. Starts back up like nothing was wrong. Normal mode no issues.
Did you found what was wrong?
New turbo's new coils ,plugs ,vanos ,new battery not done the update 08 e61. Help me. I'm loyal to n54. Don't make me e60 m5 out. Cause I've got my eyes on one love ur channel God Speed
Good day sir, my bmw fl10 has this tendency of cutting out power when I come to a stop. It's performance is still okay but it cuts power when coming to a stop.
Can you help please?
Did u figure out the issue ? I have same problem
Thanks for the video. I have an E60 25i n52, it's cranking but it won't start. I had some cams errors, I replaced the 2 sensors, now the cams errors are gone but I have a p1024 valvetronic error.. the engine is still not starting. Don't know what to try.. Any ideas?
The valvetronic-sensor (it's NOT cheap) can be the problem and when you're already there, a new valvetronic-motor is always better. And try looking at the crankshaft-sensor, the ECU wants to know is the engine rotating.
Disa valve for mine issue
Run away just run like a wolf I like this guy and he's absolutely correct mechanics are like wolf's in sheep's clothing waiting for the stupid 😅
Yo in our center console, theres a vent and a random hole? what are they? vent for air?
Thanks great information!
Chinese parts are a sure way to ruin your engine!!!
Amazon sells a lot of Chinese parts which have OEM parts manufacturers names on them!
I had problems with an oil pressure sending censor. I replace it with a beck Arnley twice, come to find out it was made in Taiwan. So I had three times the work to R&R them, scared the wholly hell out of me on the highway cruising along 90 MPH.
Though I had lost all oil pressure and blew out all my oil!
There was actually nothing wrong with the my M54!
Well I learned to check the country of manufacture on all my parts!!!
I was lucky, never buy Chinese parts, Never!!!!
Thanks again great info!
thanks for that you confirm what I'm saying all the time
Can a bad battery make your car run rough
👍
N42 engine?
How much for the update
I have a 2013, BMW 128 with only 30K miles. At idle it will randomly make what feels like a mis fire or "shudder" and I can see the tach briefly dip about 150 rpm then bounce back up to normal also, when accelerating in 3rd gear or higher If you open the throttle too much you will also get this shudder or mis fire feeling. If you mash the throttle to the floor it's better...you might get only one 'thunk" and then it runs perfect all the way up to red line. there is no CEL on the dash and scanning the car reveals no codes except for the "dirty air open and close recirculation on air cond" sensor. What the heck is wrong?
People talk bad about these engines but I was working on my friends 5.7 hemi which he claims is supper strong and durable but the n52 is built 100% better than that thing
Except for the hydraulic lifters in early production models of E90.
I really like your videos I’ve learned a lot my only problem is your music in the beginning if all possible have any other music without cursing or profanity. Thank you
You will never find that on this channel I love profanity and cursing
Quite savage aren’t we mate? 😂
Informative videos nonetheless.
Also why don't you talk more on 750Li bmw cause you always talking about the smaller bmw
Bruv thank you for your information but your video make me so worried and not wanna have a bmw 😂 joking
You can do it!
Can i get some Forte sent to me please
Thanks nigga
no problem my friend
Don’t trust this man knows what the fuck he is talking about, he’s very angry... Naa I’m kidding homie gave good advice...
