Please help with diagnosis!
A while back I had some timing belt job nightmares. Long story short I took it to an Indy shop who didn't know what they were doing. They messed up the timing and after several attempts I finally took it to the Audi dealer to have it done properly. The timing was adjusted and corrected, the camshaft position sensor was replaced, and the car is no longer misfiring. However, I still got a CEL and pulled the following codes:
17930 - Camshaft Adjustment; Bank 2: Malfunction
P1522 - 008 - Implausible Signal - Intermittent
17927/P1519/005401 - Camshaft Adjustment Bank 1: Malfunction
18404/P1996/006550 - Friction too High; Intake Cam Adjustement Bank 1
18406/P1998/006552 - Friction too High; Intake Cam Adjustement Bank 2
The car seems to be running very smoothly. I searched but those who had similar codes always had major problems that were easily identified so I couldn't find an exact answer. Could this have to do with Variable Valve Timing actuators? Any ideas??
BTW, the car is an '02 3.0Q Tip

There is a technical bulletin that your dealer can use to help out. On 3 liters there can be an issue with an oil leak from the bolts that hold the cam adjuster together. Sometimes they leak and that generally means you can replace the o-ring seals, sometimes it's a little more involved and the adjusters may need replacement.
