If one bank is misfiring and there is no code for cam position, it could well be the ignition module for that bank. Look on the air box for the two modules, swap the harnesses from one module to the other then see if the mighty VAG reports misfires on the other bank.

I agree, You should test the module.
If anything just to say you did.

i just wanted a second opinion or two on it before i decided, the limit for the engine parts is only 3300 and 2200 for tranny and 1500 for the differential 500 for electrical and 500 for ac. and that's only only thing im worried about it just doesn't seem like it would be enough limit for an Audi. Isn't the turbos failing about 6000 to fix???

Thanks for all the help btw everyone. Im going to check those ignition modules today and ill post back if anything changes

Check Engine light on 2008 Audi A6-Random misfires
 

I have owned my Audi A6 for less then a year and it is at the dealer for the 3rd time in four months with a "check Engine Light" The Dealer says the vehicle has random misfire, adds a fuel additive, drives it for 60 miles, keeps it overnight, does a cold start in the morning and tells me everything is ok. After going through this entire process 3 times in 4 months....It is not OK. Audi has sold me a Lemon and will not admit they can not fix the problem. I am so dissappointed in the lack of customer service that I have received from Audi of North America. I have wanted the A6 for the last 5 years, it was my dream car, but now it has become a nightmare....I have asked Audi financial for a refund for all the days my car has been in the shop. I keep getting the run around from everyone at Audi, the Dealer (Audi of Downtown LA), Audi North America and Audi Financial. Why should I be paying for a car that is constantly in the shop? Any advice? :

You already posted, yes? Did they rebuild your engine, are you the same man? Pick it up and take it to small claims court if lack of use cost you money.
