Need URGENT help on my used 2010 Audi A4 please!

[jozheng]

Hi all,

I recently bought a used 2010 Audi A4 2T at 85k miles and the engine has been really rough. Its misfiring like crazy and I was getting different error codes every time (cylinder 2, 3 misfire and camshaft sensor). I went to mechanic shop and replaced the camshaft sensor for 200$ and also did my own sparkplugs and coilpack change. Now I get error codes P0341and P0342 Camshaft Sensor Bank A circuit Range. The misfire is still not going away and today, I got a new Error code: P0016: Crankshaft Position - Camshaft Position Correlation Bank 1 Sensor A. I paid another 120$ to the mechanic and he say maybe it needs to replace timing chain and maybe entire engine.

The mechanic suggested me to go to Audi dealership and helped me reset the light only. Now whenever I drive and accelerate, I often get the EPC light flash and my car vibrates. I really don''t know what to do, I've already spent about 1000$ trying to diagnose the problem and I can't seem to find out whats causing the misfires. Also, there is a noticeable rattling sound coming from the engine and it was not there before. Please respond and give me some insights, such as what could be the cause of these misfires, how much would replacing the timing chain or entire engine cost? Should I go to dealership? Anything helps.Thank you!!!

[jozheng]

Also, my car has 85k miles and its a 2010 Audi A4 Sedan 2T (this is what websites like CarFax and Vehiclehistory show as well). However, when the mechanic plugged in his OBD computer and automatically detect the VIN, it detected a 2009 Audi A4 Avant with 135k miles with the SAME VIN. What could be causing this discrepancy? Did the owner reset the odometer? Please respond and thanks in advance!

I can't be much help, but I would probably just take it to the dealership to have it diagnosed. Once you have the diagnosis, you can take it to an independent shop to have the work done.

I know there is another thread about the cost of replacing an engine and I am pretty sure there is a thread on the timing chain.

[mtroxel]

Misfires, cam errors and a rattling sound? Stop throwing new sensors at the car. Take it to the dealer and find out what's going on. If the rattling sound is a timing chain that has jumped, you might even tow it to the dealer. Next time you touch the key could be the end of that motor. Seriously. If timing jumped, what's to keep it from jumping again and valves hit pistons.

“...every week it seems like somebody new says “I just bought a 2010 with 90k miles and now the mechanic/dealer says I need a new engine.”

Sorry OP!

And (again) now for my obligatory PSA: To all those reading this...never buy an Audi B8 (2009-2012). Please!!!

^^^
It's not the b8 it's the inability of new users buying b8's without doing an ounce of research. They deserve what they get if they run with those codes and misfires. 5 mins of research will tell you all about the timing chain. So it's buyer error not the car

I wouldn't say never buy a b8. If your incapable of research and being informed then don't buy a b8

I just hate to see people lose money like this.

[LTopher]

If that were my car, I'd pay to have it towed to an Audi dealer. The rattling could indicate a stretched timing chain (lucky the engine hasn't blown yet). If the problem is something else, I'd at least have the dealer look through the inspection hole on the timing chain cover to see what revision chain tensioner is in there. If it's not the latest K revision, I'd have it replaced.

I wouldn't say 'never' buy the car, just do your homework first. I knew about the chain tensioner and oil consumption issues before buying, so I planned on spending some extra $$$.

[boostk420]

You check spark plugs? no way it needs a new engine at 110k. I would do spark plugs and coil packs first.

Ah have you searched the B8 forums.There are lots of owners who had way less km than that that needed a new engine.B8 is a good design but the oil consumption and timing chain tensioner killed the reputation .

2nd. My 2009 A4 needed a new engine at 80k and now my 2010 A4 had its engine rebuilt at 23K miles, then again at 50K miles last week and it goes in for a new turbo today after work.

Wow, I'm surprised you're still in this for the longhaul. A new engine and two rebuilds on two different B8 A4s? I'd gladly get rid of mine for a B8 S4 if shit starts going haywire. I'm at 130k miles and it drinks about a qt of oil every 5k oil change but if it gets any worse than that it's bye bye 2.0t, with a smile

Granted I have had the tensioner and clutch/rms done so I'd like to keep it at least another 25k lol

^^This! If the Timing Chain Tensioner has failed or your timing has jumped then your motor could literally destroy itself the next time you try to start it.

Tow it to a shop or the dealership. If you are a DIY kind of person then you can pop open the inspection port on the lower timing chain cover and take a look at your tensioner. As @LTopher said, if it's not the latest revision, you'll need to get it replaced.

I've had a 2015 S4 and 2013 S5 and 2016 A6 all with the 3.0T engine and its been bullet proof. dual pulley for thousands of miles and no issue at all on any of them.

The A4 I have now is an Avant and I'd have an S4 Avant instead if we could have them in the USA. Luckily on this current A4 everything has been covered so far by Carmax 30 day warranty (and previously by Audi warranty) but if I have another engine issue down the road i'll likely just transplant a 3.0T/DL501 in this avant.

Otherwise, yes my opinion is that the 2.0T is a complete POS engine and I wouldnt advise anyone to buy an A4 made after the good ole B6 days ;)

Haha yeah I have certain regrets buying my 2010 but overall it's been pretty solid. I do enjoy hearing the positive stuff about the 3.0t, I'm fairly confident that's my next purchase. Any issue I've had with this car has been related to the engine and nothing really with the suspension/braking/interior. I have two good friends that work at the local Audi/VW/Porsche dealership in my area. They both speak highly of the 3.0t motor. One of them has a 2016 S4 and loves it. The other one has a 2018 A4 and that car is just a totally different beast compared to these older 2.0t motors. It's pretty damn impressive stock. The day he bought it I drove it and was just blown away (even being an auto, lol)

I see you've only owned your audi since November 27th (yesterday), you'll figure it out in time. lol

[b6onboost]

I believe it.

There's a handful of people in the B9 A4 forum who've came from 3.0T S4/S5s/A6s and claim the B9 A4 2.0T performance doesn't feel like a downgrade at all. (Not trying to incite any arguments, just saying the new 2.0T must be pretty strong.)

Yeah totally, I haven't actually driven a B8 S4 unfortunately so I can't compare but the whole experience from the beautiful interior/google maps cluster/power delivery and extremely quick shifts out of the B9, I can see where you may not feel like a downgrade from the 3.0t. Believe me when I say the transmission is so smooth you CANNOT feel the car shifting at all. It's just constant power all the way through the gears. I would actually consider a B9 an option if I had the cash, and I'm a diehard manual guy. I mean the tech in the B9 makes my B8 feel like an early 90's Plymouth Acclaim.

Here's a shot of it the day he got it taken with my Pixel. I absolutely love the look of the new B9's, subjective opinion of course. Actually driving it is just a whole different experience compared to the B8. He of course has lowered it and already put new wheels on it, I was trying to get my hands on those stock wheels but he won't let them go



Apologies for steering totally off-topic with this thread!

[b6onboost]

I need to drive one. I keep telling myself not to bother with another A4 or 4cly, that I need an /S or FI V6/I6, but the A4 just keeps improving.

Back on Topic...

OP have it towed to a dealer. Have them scan it and check the timing before trying to start it again. It'll be worth the diagnostic fee to know what's wrong and potentially save it from further damage. May just need a tensioner and timing adjustment, or your motor may be toast from running with incorrect timing as its an interference engine. And whatever the repair needed is, find a good independent shop and have them do it a lot cheaper.

I see you've only owned your audi since November 27th (yesterday), you'll figure it out in time. lol

I see your quick to call people out. I've owened 10 Audi's since I was 21 now I'm 27. I have had 2 s4s. But mostly stick with the 1.8t now a days. Its okay Maybe I don't know b7 and b8 but I can run circles around you with the b5 and b6. :)

Not talking about how fast your car is, im talking about how unreliable B7's and B8's are. No one buys a car with the intention of replacing a HPFP cam follower every oil change, or water pump every 25k, or timing chain, or adding 2 quarts of oil every 1000 miles, etc etc etc and then some.

I think Spawne was just making sure the OP didnt make a huge mistake taking your advise that there is "no way its the engine" and continue driving his car resulting in 4 grand in repairs if it happens to be a more and more common cam timing issue.

Welcome to the B8 A4 though. The 2009 to 2012 B8 A4 is pretty notorious for having absolute shit engines... like class action lawsuit and audi admitting 126,000 engines were shit. Like stickies at the top of the B8 A4 forum with a 119 page thread that has 850,000 views filled with only stories about folks getting piston or engine replacements because of the crap engines. I think you made a wise decision on your 1.8t ;)

. This is my winter daily driver. Will drive it all winter and sell it next spring and use that $ to do some more mods to my B6 that I park all winter due to the salt and corrosion in Vermont. :)

I’m all for going a bit off topic - but now its like grandpa’s slide show...and salt and corrosion?...boring. We dont have that lame as* problem in socal.

Isn't that good reason to kill the reputation? That is SERIOUS stuff! When it is common for an engine to need IDK, $8,000 in repairs (more if the tensioner goes) at say 50,000 to 70,000 miles, that is piss poor! It is a horrible engine.... one of the worst in modern times.

[mtroxel]

The B8 2.0 is a train wreck. We all know that. My B7 was the most reliable Audi I've owned. Far better than my 2 B5's. I did nothing to that car. Changed a cam follower, a timing belt and a PCV valve. 140,000 miles.

[A4Qwattro]

I think there needs to be a "Do Not Buy" sticky here for 2009-2012 Audi A4. Even on an Audi forum. It's like Audi flipped a kill switch in the last month on a few more of these B8 cars in Audizine and Audiworld forums. All the same symptoms of shaking idle, misfires, etc.

Fine, some Audiziners are doing just fine with their '09-'12 but risk seems unacceptable. People who own a lot of Audi's (including myself) tend to become desensitized to what is really unacceptable from an automaker. They get used to replacing timing belts or timing chains, or whole engines. New issues don't really scare them off...but it's still insane. No one should be happy to go into a dealer for a free piston replacement....What sort of confidence is that supposed to inspire? There a better cars out there.

The average consumer looking for a daily driver should not buy an '09-'12 Audi A4. Regardless of some people here not having issues or doing Stage II or replacing the tensioners, injectors etc. The entire ownership experience is just not worth it unless you simply must have an Audi or want the A4 Avant from those model years

With that said, if you still are determined to own this car, then open your wallet and a trip to the dealer will resolve this in a lengthy and frustrating experience...Alternatively get rid of the car. Do not give a dealership or Audi your money for a car that was flawed from the factory. Why should you pay to fix their problems?

[boostk420]

Trust me it sucks Vermont is one of the few states who still uses salt and brine on the roads. Being a car lover I always buy a winter a4. Park my summer a4. I will make a profit after running it all winter when i sell it in spring, then use that money to do more mods. Let alone the life expectancy I will increase by not driving it every winter. Next is cat back exhaust. Catch can and r8 coil packs.

I think you're ignoring one of the best features of an Audi. The galvanized body. They salt even more where I live, I rarely see an Audi under 10 years old with rust. I had my 2 B5's for well over 200,000, no rust on either one.

[boostk420]

Really??!! That's awesome! I did not know I thought only portions were galvanized steel. Either way I still like to park it due to quarter panels and etc getting destroyed from salt and brine on the road. Thanks for that info ! Still I noticed my sub frame and rear subframes on my winter a4 still attracting a lot of rust.

galvanized steel bodies of cars have been around for decades, this isnt unique to audi, what keeps our cars rust free for longer is alot of things, better undercoating procedures/materials, splash shields throughout the undercarriage of the car, as well as changes in the types of road salt used for snow in the winter. Not to mention alot of newer cars, as well as some parts of the B8's and newer audi's are using aluminum on alot more parts, particularly suspension components. But I still have a pretty decent share of rust on the under side of my 09 B8 which is going on 9 years old, and these cars still have issues with rusting on the trunk lids in certain corners.

[boostk420]

I guess too in my case both my cars are over 10 years old so I will be carefully with them in the salt and winter. I do undercoat my cars myself with amsoil HMT. Heavy metal treatment. Which they use in Europe its meant for motor cycle chains.
