I really like this guys video. He stays on track, no stories about his cousins uncles landscapers Audi was doing this or that. Straight forward. Here is the part, this is what it looks like when it fails, these are the codes it will trigger and what to do ie. change said part or just the gasket. Great delivery-he should do this for a living.
Much respect and thanks for acknowledging my work!
I wish there was a video like this when I bought my b7 I’ve had to deal with everything on this list the hard way 😂
Wow! Yea, some of these issues are a pain to fix, lol
Same bro
I am currently checking all these jobs off lol
More universal b7 problems: driver’s side seat back will come unglued for no reason. Passenger glove console hinge will break on the rightmost side. You’ll lose a quart of oil every 1500-2k miles.
That happened to my driver side seat too
Mine too
both driver and passenger side for me lol..
The arm rest eventually breaks, the battery compartment fills with water because the holes at the bottom are obstructed with dirt...I can go on if you give me a few mins to think lol
The oil dipstick pull ring breaks because it's made of plastic, the overflow hose that runs from the coolant bucket to the radiator, the little nipple that fits snug inside the hose to then connect to the radiator goes bad. What a problem to have. If you didn't know any better you would go to Audi and buy the hose with the clamps and think it's a 10 min job. WRONG. The flex pipe cracks like every 2-3 years no matter what you do.
Heck yeah! I fixed four out of ten so far..
Thank you so much for the work you are helping us all out with ..
I'm happy to help, much respect 👍🏽
This was a clear and concise presentation. Good job!
Thank you!
Brilliantly clear and narrated video. Thank you. Perhaps one other point to include is to ensure drainholes in plenum chamber below windscreen are kept clear....
Great video with links to each problem. Thank you. I’m in Canada and there’s a snowstorm today. When I powered the engine and started driving the rpm was moving up and down between 1700-1800. I don’t know why but it only started doing this today. Yesterday it was fine.
Thanks for watching! Did the car throw any check engine light code?
Very smooth and interesting to watch! Respect 👍
Thanks for watching, much respect!
Thank you so much for these awesome videos for us B7 owners!
Definitely, I'm happy you I'm able to help!
Very clear and consice overview. Glad to give you that 1000th like!
Much respect, thanks for your support!
Great video! I've basically done all of these fixes on my Audi A4 B7. They are honestly pretty cheap and cheap to diy. The coolant flange is a PITA for sure. The AC issues are usually the internal servos failing to turn the car to recirc. AC will only work like 80 and below. After parking it's bad. That's because it sucks in super hot air from the front instead of inside the car. You just have to pull the motors off the flaps and spin them a few times. Ac fixed! Love my B7 but she's a maintenance queen.
Yea, these cars can run well, once you keep up with the maintenance. If you can do the work yourself, it makes it a lot more affordable to own.
Shawn,
AMEN! I sincerely have a love hate relationship with my Audi. It is a phenomenon performance car but I there are times where I wanna light a match to it and walk away. lol
Okay so what’s the reasoning for the ac being bad in the b7 break it down please
My grandmas ac in her 07 does the same. But also noticed a faint smell and not sure if there is a filter to change cabin filter or anything for ac? Maybe a mouse died in there. She just got it. So noticing it all day by day lol. Needs flex pipe. Diverter valve. Lol
Same here. About to take on all of these jobs… and a timing job. Unreal how exact this video was to the problems that i have at 118K miles LOL
Awesome video. I agree with you about the coolant flange- it was a nightmare to fix but doable.
Yea, for sure. I recently made a video explaining how to replace it.
This was a very educational video, I’ve had issues with numbers 9,8,6 and the booster vacuum hose.
Much respect! Yea, keep an eye on the rest if in the mean time.
Very very good video. Precise and even layman's can follow you. Excellent teacher.
Much respect! thanks for watching
Wow this presentation is amazing probably best video on faults like this 👌👌
Much respect and thanks for the acknowledgment!
Thanks for a great video! I'm looking at buying one of these cars, I've always wanted one and they are now at a price point I can afford. I've always been told to stay away from older Audi's due to "problems" but after watching this, it seems like these issues can be fixed with a little effort.
Yes, and I've made videos on how to fix most of these issues.
Thanks for the video, I finally understand why one of my ignition coils fail every year.
Bro. Your video is amazing. I'm after one of these at the moment, so will study it carefully. Thank you for your efforts 👌
Glad it was helpful! Thanks for watching
Excellent video, I just replace the timing chain and tensioner, coolant flange with heater core hoses, oil filter housing, thermostat, valve cover gasket, cleaned the intake valve and also changed the oil. It was quite the job but save me a ton of money. I’m going to rebuild the turbo next.
Yea, you saved your self a ton of money for sure with all that work. If you're just replacing the cartridge in the turbo, it's pretty simple. The only challenge is getting the turbo off the car and even that is not bad.
How much did all that cost to replace?
Great video, very much appreciated, I have a problem of rough idle and just recently oil in the water bottle whilst the oil in the engine is ok.
Thank you so much your videos are so helpful , very detailed & clear to see . Just had my brother change my valve cover gasket & spark plugs with your help , will check on the PCV in order to see if that’s why the vehicle is still idling .
Thanks for watching! I'm happy you find my videos helpful. Yea, definitely check it.
This channel should have more followers, nice and clean explanation!
Much respect, I appreciate you acknowledging my work! Thanks for watching.
Bois are running on battery now😂
Great tip, thanks. Sure I'll come back to this vid when I'm ready. Right, to check out your others...
For, sure. Thanks for checking out my content!
Very useful and well done video. Thanks for the tips and the replacement videos.
Much respect and thanks for checking out my videos!
im really glad u made this vid!! thank you!:)
Great video, my car is ruff when idling. Great information and will be checking on my PCV and coil pack :)
For sure, I'm happy you got value from this.
Very helpful video. I wish I saw this sooner.
Thanks for watching!
Thank you. great video. Had to do the PCV and the purge valve. Good DIY
Much respect 🙏
I have been doing all my own maintenance on all of my cars for over 40 years. I recently acquired a 2006 Audi A4 B7 from a relative.. 63K miles and I've already done 3 of the items on your list.. Was wondering if you have a video of the rear coolant flange R and R? That is leaking on this car and it is my next goal! By the way, I really like your videos! Straight forward and you explain in enough detail the important steps..
Very informative. Thank you.
Much respect and thanks for watching!
Thank’s for the heads up. Going to look at an Audi A4 2.0ltr petrol model & this is definitely going to help
I'm happy you found this video helpful! Thanks for watching.
Great vid man very helpful
Thanks for watching!
Awesome video very informative since i just bought on avant with an oil leak that i feel will be the oil filter housings
Good stuff i subscribed
Much respect! Yea, I made a step-by-step video on how to do the replacement. Welcome to the Crafty family!
I have a 2006 Audi A4 B7 - 6MT 2.0T, at 436,000 km's. I have Coolant flange failure, cylinder 1 miss fire. If I can get these issues fixed the car is perfect lol I hope it hits the big 500K. Thank you for your videos, you made this super less stressful and straight to the point. The amount of anxiety washing away as I watch your videos, priceless! nice content! saved a daily driver :)
Yea, definitely do the maintenance to keep it on the road and reach your goal. These cars can last if the common problems are addressed. Much respect and thanks for watching!
Damn that's over 250k miles here in the U.S. I may be getting a b7 cabrolet with only 146k miles. I'm stoked!!
I had the same problem, come down to it being fuel injectors. Changed out myself. Put Bosch fuel injectors for audi a4 2007. Now runs great. New coil packs didn't fix the issue. But with new coil packs, spark plugs and fuel injectors, at 140k miles it still runs A-1!
@@Ej6daniel I have an 08 Cab. I'm rebuilding it from front to back. I got it for 1k(engine was shot). When I'm finished she will purr like a kitten 😁😁
@@grimbarbier1342 will fuel injector cleaner help any or is it best to just switch them out all together ?
Great video. Keep up the good videos.
Much respect! yea, I definitely got more videos in the pipeline.
Great video.
Thanks!
Ecellent content great value thanks dude
Appreciate it, thanks for watching!
Very nice explanations
Much respect!
Yes Bigman appreciate the video great detail
Much respect fam👍🏽
Awesome video man, yeah I have had a lot of these repairs hahaha.
Thanks! Yea, Once you fix or pay attention to the common issues, you'll be good.
You’re awesome, thank you.
Thanks for watching!
Just awesome! Thanks
Much respect!
Greate video, very informative
Much respect, thanks for watching!
Great video!
Much respect!
i am very impressed with the video although i think we can also add to the top 10 list the notorious failure of the TCM in these cars.
Been through all this and more, I believe the n75 valve is also an issue, for lack of boost. There's also loads of problems with vacuum and boost leaks, my latest set back has took weeks to find and then I found another. Firstly the crankcase breather hose was split so fixed that, then find my vacuum pump is leaking oil and also pulling air so another vacuum leak. Hope this information may help someone. Great video btw, wish I'd seen this before I bought the car 😇 Would have still bought it, love the old beast 😊👍
Yea, these cars will run good once the maintenance and common issues are addressed. Yea, some boost leak can be a nightmare to find. Did you replace your timing belt? Thanks for checking out my content.
Timing belt was done about 10,000miles ago along with the water pump and tensioner, the timing chain was done about 7,000 miles ago also the chain guides, chain tensioner, thermostat housing and cam follower. Why ? ✌👍
@@gustyclayton2498 Nice! I notice you didn't mentioned it in your intial post. Yea, once you did timing already your pretty much ahead of the game.👍🏽
Great video
Thanks for watching!
This is a great summary of everything that happens with the B7 and what I have experienced thus far. If I dare to say, I would add the faulty turbocharger. I had to replace mine after I replaced the diverter valve and kept getting the P0299 fault code.
Also, not too sure if this applies to anyone out there but the cleat coat and paint on my hood started to flake off on the passenger side probably due to the faulty turbocharger.
Factory paint is just crap in general I've found
My turbo is going. Who h sux cuz i have a code and cant get s sticker unless i get a new turbo. 1k for a $30 sticker is hard to justify lol
@@chasewilson277 but turbos go stutututu
Good video bud!
Much respect!
The best video audi problems
Thank You for the video....
Much respect 🙏
Great vid, I have done most of these fixes, currently I keep carbon fouling plugs. I replaced coil packs with the red bosch from ECS. would getting a hotter spark plug fix it? Do you think the injectors are bad? I would like to do carbon clean up on intake, do you have video for this? The car has 113k on it. Also maybe change the the fuel filter/pressure regulator? All the plugs carbon foul, then car stalls, Im getting misfiring and running rich codes. What do you think?
Literally just bought an 08 a4 and had to send it back the day I got it cuz of the coolant gasket failure. Definitely gonna press them on if they maintained the rest of this stuff now, extremely useful video, gonna save it for future maintenance use👍
Yea, definitely pay attention to all the common problems. Thanks for watching!
I would add the wastegate flapper to the list. It's a bit harder to fix, but not impossible. If the turbo is otherwise good, it's worth fixing rather than buying a new turbo.
What you think about upgrading to a ko4 turbo?
Have had several of these problems . Coolant flange leak 2x . Also the transmission Mount gets loose. I still love my a4 b7 .
Good job thank you
Much respect!
Just subscribed my boss. Yuh sound like a yaadie. Everything you touched on i have done on my car. It makes for a trouble free.. Worry free..peace of mind experience. Great video, to the point and helpful. How can you differentiate a misfire due to carbon build up?
Much respect, yaadie for sure! Yea, it's good to keep up with maintenance. The carbon build up might prevent the valves from closing properly. Once you rule out everything else that might cause the misfire, you could visually inspect the valves or do a compression test.
Thank you
Hello from Chile .yo tengo ese problema de la junta de la tapa de las válvulas se me desliza el aceite por el borde hacia atrás y cae al múltiple .se empieza a quemar y sale humo .pero ya la soluciono,gracias por el video saludos desde Chile.
Nice work. I’d add cam chain / vvt seals, vacuum pump gets loose and rattles u can rebuild it for cheap or buy new
Yea, nice addition to the list 👍🏽
Thanks Yardie!!!
Much respect 💪🏽
so helpful thans bro
Thanks for watching!
I had literally all these problems now I’m 1400 in parts :)
Wow, If you do the repairs your self that will help to keep the cost down.
Buen trabajo primo
Gracias!
you seem to have a great understanding of the b7 platform. Do you happen to have any videos on fuel injector replacement on the 2.0?
Thanks
Much respect and thanks for your support!
I have 104k and have done the timing belt with water pump, a couple of the ones you mentioned. Recently the ac compressor failed and have to replace that but fall is here so no hurry with that now. The plastic coolant hose on the back side of the engine concerns me after watching this. The cam follower for the fuel pump is a must do and will do again in 50k more miles. Nice looking car but continuous maintenance
If it's not currently leaking any coolant, keep an eye on it. Yea, you gotta keep on top of the maintenance, in order for these cars to keep going.
Thanks! I love my b7 and that’s funny I got hit with 3 of those common issues last year 💀
Yea, the b7 is a nice platform.
Thank you kind sir...
Welcome!
Nice video, I would maybe add the rear cam chain, as the tensioner is prone to failing.
Thanks! Yea, true. The rear chain is a common failure too, and the bolt is a pain to crack loose.
Your videos are really well done and easy to follow. Thank you for taking the time. My Audi A4 B7 consumes a lot of oil. I have also heard that these cars are notorious for oil consumption. For a long time I was having to replenish the oil every 800-1000 miles. Then at some point it dropped to less than 500 miles to a quart. When I noticed that the VCG was leaking oil onto the engine and into spark plug wells. I managed to successfully change them thanks to your video. However I sense the car is still burning oil than when I first got the car a few years back and wondering if it might be connected to a faulty turbo seal. the car is not throwing up any error codes. However, the other day I was getting on the highway and the car felt like it was having a slight hesitation around 2k rpm for a few seconds. then I saw a spew of grey smoke and noticeable smell in the cabin . Then all clear and car was driving fine after that. It's happened a few times. Almost like some kind of a buildup that needs to release every once in a while. There is a hole in the muffler which I plan on fixing. if this was a sign of a turbo going bad should I expect an error code?
To follow up. It turned out to be a crack in the valve cover itself. Found one at the junk yard. Since then smoke issue resolved. Oil consumption much much better.
I don’t know where the oil goes in mine???? It doesn’t smoke . No visible signs of leaks?? It just goes off into another dimension.
@@kenalderson568 If you're getting above 2000 km per quart, I was told by several mechanics that this is normal for this engine. Though I have a friend with same car who doesn't seem to experience any oil loss at all. So, who really knows. However, if you've experienced ever-increasing oil consumption over time, check for cracks in the valve cover itself. Especially, along the edge near the PCV valve outlet. That was my issue and restored my oil consumption issue back above the "normal" range.
I’m glad I came across this video. I just took ownership of a 2007 A4. The very first problem you discussed was spot-on, now I know why car takes a few tries after refueling
Awesome work! I have been experiencing loss of power while driving where its like the car is holding itself back from when the turbo kicks in.
how much psi the car making at full boost?
@@CraftyWorkshopBuilds What I have seen is its around 9-10 PSI when Im shifting up as I drive (I really dont push it that much). After that it remains near 0 if Im cruising without adding much power. So far I have a check engine light as well but that is going to be looked at next week on Monday. I may have to pay more attention to the psi and I can get more information tomorrow.
@@edwineliel Okay, what check engine code did you get?
Possible cause: If the diverter valve is torn, you will experience loss of power.
@@CraftyWorkshopBuilds I just checked this morning. I have a P0299 code. Diverter needs replacement?
@@edwineliel Yes, replace it.
I just replaced the purge valve & the camshaft position sensor. My car would smell like gas in the cabin every morning. It doesn’t anymore but if you have any tips on what else I should look out for it would be very helpful 🎉
hi ur doing , i replace the high pressure fuel pump on audi 4T 2005 2.0t and it does not accelerate like before it only like 50% of the power and it's chocked down when i'm driving , do you have any tips how to fix this issue , 👍🙏
BTW your video was so useful and educational , it will save alot of time and money to all your doit yourselves out there , thank you and keep up the good word 👍💪🏻
Omg this is so true!!!
Dudeeee yes thank u!
Sure, no problem. Thanks for watching!
Great video. Well done, easy to follow. Question I keep getting the P0102 code for the mass airflow sensor. I changed it with a brand new OEM part. Still getting the code. And ideas? I got a K&N air filter in the car, new MAF, premium fuel, new air box. Was gonna do the MAP sensor but I don't know where it is. Any help would be appreciated. Car bucks when you floor the gas. My wife test drive it and she mashed the gas pedal. The tachometer went all the way to 7000rpm The car bucked a couple of times then light went on. When I drove I get no lights but other p people have had the problem. Trying to fix it cause I'm selling the car and don't want to give someone else a car with problems
Thank you...
Much respect!
Hello mate , apreciate your Videos , you are giving us some precious information:D keep up the good work :D , I have a small question if you dont mind , i have an audi a6 c6 2.0 TFsi , and EPC light sometimes appears and my car enters in Limp mode .... somethimes is working corectly, some mechanics told me that is electrical problems . i have changed the Relay 614 and my car worked perfectly 2 month but now again my relay is burned out .... when i touch the Relay 614 fells very Hot . do you maybe have an Ideea regarding what should i check please? thanks a lot
I quickly got rid of my Pcv valve with a catch can. Never went back. Also replaced the n75 with GFB+ diverted valve. That will probably last for ever. Also a base tune made the car run better too. Im my
Opinion. I have an 06 BPG motor which is the only year of the belt driven 2.0 which I prefer as the guides on chain motors need to be changed anyways.
Yea, the timing belt is easier to replace compared to the chain on the newer motors. But, the newer TSI is a overall better platform.
Thanks for the info. Would you know how I can get rid of the P0102 code I posted about. Changed the MAF air filter air box and the pcv. Any help would be appreciated. Do you have a video on the catch can?
@@CraftyWorkshopBuilds hello I ask your opinion. I changed the timing belt and mn audi cvt tranny and well since the transmission slips my impression, the rpm is high but the audi moves slower like a loss of power and when it is in sporr mode the speeds go jusau 6 to 55kmh do you think it could be the timming?
Just picked a A4 up for 800, pretty sure it’s checked off the first 4 of these issues
Changed the spark plugs and ignition coils and im still getting a cylinder misfire. Is there anything I should check next?
Good video! Question, i have a A6 with the same engine. Is it possible to change timing belt ( front ) and cam chain ( back ) with engine in the car? Or must the engine be removed entirely? Keep up the good videos! 👍
you could definitely do the timing belt with the motor in. I'm not sure if you'll have enough space to remove the bolt for the chain at the back. But I was able to remove chain on the b7 audi with the motor in, it was a tight fit for my tools, but it worked.
Just watched this and subscribed 👍
I have A6 se 2.0 tdi and threw a P0299
I will check hoses to intercooler and also check that diverter valve ….
Thanks 🙏
Is there much difference in location of DV on A6 to A4.
Much respect and welcome to the Crafty family. I'm not sure about the exact location of the diverter valve on the a6, but it should be on the turbo, attached with three little hex bolts.
you should of added the leaky vacuum pump to the list.. vacuum pump is notorious for leaking depending on what revision of pump you have too.
My 2008 A4 was at 100k miles and my shop said I needed new engine mounts. Is this normal? Other than that I get messages to close my gas cap a lot. Thanks for the videos.
Love the videos and May be you can help.. The number 1 Coil pack short circuited on my 2.0T 2006>
We changed the coil, but now its not firing up the engine. The engine turns/ its alive as though it wants to start but its no firing up. Any ideas?
There re no error codes or blown fuses
Any more details?
is this diverter valve can cause turbo and exhaust manifold getting red hot during normal driving?
What are the torque settings for the valve cover gasket?
I have a audi 2007 a4 2.0 turbo i was driving it on the freeway and the car started shaking a bit then turn off it crancks but wount start have any idea of what i should look for
Nice video. Watch out for cheap chinese parts, esp EGR valves.
Hi guys I have a B7 dtm and was racing the vehicle today and the clutch was riding on 3rd gear high rpm is it normal when it's hot or do I have to replace the clutch please advise
Can you do a video on how to replace thermostat and also the cooling fan assembly for Audi A4 2007 please and thank you
Good video! Question … do you have any video to share how to replace the diverte valve that you mentioned as the last item of your video? Thanks in advance
Thanks! I currently don't have a video on replacing the diverter valve, I'll see if I get the chance to make a video on it.
@@CraftyWorkshopBuilds would be awesome! Cheers
One thing you might wanna add is the n205 valve..
By any chance anyone know what's the main cause of the epc light on 2007 audi a4 quattro 2.0t b7
Good thing parts for this car are cheap and super easy to work on 👍
Yea, the 4 cylinder engine allows alot of space in the bay to work.
@@CraftyWorkshopBuilds have you ever replaced the timing chain?
@@steezyg9746 These engines have a timing belt and a small chain at the back.. sometimes the tensioner on the small chain goes bad and will need to be replaced.
Yes, I've replaced both the timing belt and chain on these engines.
@@CraftyWorkshopBuilds I keep seeing b7s with the timing belt or timing chain so idk which it is. How was replacing that chain on the back?
@@steezyg9746 my brother and I have changed it and it’s pretty straight forward but there is one bolt that you need to take out that is a bitch.
Hey so I have a 2008 Audi A4 when I bought it it had a bad fuel pressure regulator I change it but the code still came out then it misfired I change all the coils and spark plugs later on my coolant flags started to leak slowly I haven’t change it yet but I make sure there’s always water and coolant in there.. it also has a rough idea but goes away as soon as I drive it… I was driving when I felt the car loose power and the epc light came on I pulled over and my car doesn’t start anymore it cranks but no start.. I put the scanner on and it gave me the code p0300 which is for misfiring so I change the coils and sparks again but the car still doesn’t work it seems like u know what ur talking about can u point me out to what it could be pls ?
thank for the info... good video.. my hazard/4 way flashers don't shut off..do you by chance know what possible cause.. 2006 a4 Thanks in advance
You could remove the hazard switch and check if it's faulty.
