VAG Codes

[Jerritt]

Ran my carista app and had a couple codes come back. My engine wont start and doesnt event seem like its attempting to.

P0016 Crankshaft position - camshaft position correlation bank 1 sensor A
P0300 Random multiple cylinder Misfire
P0301 Cyl 1 misfire
P0303 Cyl 3 misfire
01206 Signal for duration of ignition off time (a/c)

Thats all I got. Anyone have any insight?

Also when I try to start my car I push the start button and when I let go it continues to try to start itself for about 15 seconds even if my foot is off the brake. It doesnt crank at all.

That P0016 is the deadly one. More than likely your timing tensioner went.

Any recommendations on where to buy replacement tensioner and chain? Ive seen a few kits but they all come with covers that I dont need.

Also how difficult is it to replace the valves if theyre damaged? Can I check for damage with a borescope or do they have to be individually removed?

Sorry for all the questions, Im in the middle of a cross country move and want to do as much of this as I can myself before I go. Anything I cant do I will send to a mechanic for. Tensioner and chain seem pretty straight forward. Valves seem to be a whole nother animal

You're going to need the specialty tools, for starters. This engine is not that easy to work on and easier to make mistakes on than most. I buy the complete OEM timing parts kits from ECS for these jobs. Unless it's extremely low mileage, then I highly recommend replacing everything while you're in there. Almost every part has been through at least one design revision. If you need to pull the cylinder head, you're looking at spending close to a grand just on the tools. Probably best left to an technician who's experienced with the engine.

Figured. Timing chain and tensioner it is! hopefully this will remedy the problem.

Do you know what size socket is needed to advance the crank?

[Jerritt]

Nvm got it. 24mm which I happen to have from doing the AC sensor.

Do you know if its possible to run a compression test to see if the valves are messed up? or do we have have to inspect visually?

The only way to be 100% sure is for center line tests on valves. The next step down, would be to pull the head and see if valves made contact with any pistons. Lastly, like you said, you could do a compression / leak down check. That would sum up if the combustion chamber is sealing properly or not.

However, do you know how many links your timing jumped? I'd start there. Also, if you haven't read the DIY motor thread I started, I provide a lot of guidance and advise in it. Link: http://www.audizine.com/forum/showth...-and-front-end

Got it! Read you DIY a few times. Am starting with the chain and tensioner. I will count the links once I rotate the crank which will most likely be today. Just towed it somewhere that I can work on it. I had street parking in brooklyn and my neighbors complain about any mechanic work being done.

Got a quote today from Drive Auto for $3k for New timing chain, tensioner, guides, all new valves, gaskets, rebuild the head. Thoughts?

out of curiosity, what is the year and mileage of the car? i think we should start tracking this data someplace...time chain tensioner sticky or something? admin?

Not a bad idea. I have a 2009 A4 with 110k miles on it. All long distance highway miles (NY to LA, NY to Miami 6x etc). I was told that if they had been local/city miles my tensioner wouldve failed about 10-20k miles ago. I found someone who has filed a class action lawsuit against Audi for this specific reason. Here is what he said and his contact is below..

A class action was filed on April 21, 2016 in Federal Court against Volkswagen Group of America, Inc. and its divisions together with Volkswagenwerk Aktiengesellschaft and Audi Aktiengesellschaft for damages caused by the defective timing chain tensioner and chain in 2008 - early 2012 VW and Audi vehicles incorporating the 2.0L TSI and TFSI engines. These tensioners and chains should have been replaced under the original warranty or an extended warranty program since Volkswagen knew these components were defective and would cause premature and often unannounced expensive engine failure. This is evidenced by the subsequent revisions to the tensioner and chain performed in late 2011 in an effort to correct the original defects.
An amended complaint is being prepared to add more plaintiffs. It is anticipated the total time commitment for persons participating as named class representatives will be less than 6 hours. This commitment would consist of reviewing the service history of their respective vehicle, responding to Volkswagen’s informational requests and a few hours of deposition testimony.
There is no cost for participation in the class action. The law firms handling the case will pay all expenses and will not be paid unless the case is successful. The participation incentive for class representatives (authorized by the court and paid by Volkswagen if the class action is successful) should be between $5,000.00 and $7,500.00. We will attempt to select the best class representative from each state based on vehicle purchase history, failure mileage and date of failure. Although you may not be a named class representative, you will remain a member of the class unless you decide to opt out at a later time. Regardless whether you are interested in participating as a named class representative, you should retain all vehicle service and repair records. If your engine tensioner system parts are still available, they should also be preserved.
Although each class action has different results, the usual refrain that the class action only benefited the lawyers and they received most if not all of the settlement money is simply not true. The last Volkswagen class action case where I participated concerned engine oil sludge occurring in 1.8L VW/Audi engines. The settlement resulted in tens of millions of dollars in repair reimbursements to vehicle owners for oil-sludged engines and 500,000 vehicle owners received a comprehensive extended engine warranty covering oil sludge related damage.

Not too bad. It all depends on 'if' you need head work and what specifically needs to get done.
