Has anyone else had the following problem?
For the past two months, my 225QC has been loosing power, followed by the check engine light coming on. It always seems to happen between 400 and 600 miles after having the computer reset. I've had it to the dealership 4 times so far, and all they've been able to do is reset the computer and waste my time. So far they've "tightened some bolts", replaced the DV, replaced the oxygen sensor, and scratched their heads. Now, they think it might have something to do with the repairs they did (twice) to my fuel sending unit. The idea is that the pickup in the gas tank is sucking air, causing the lean condition.
The code that the computer is giving is
17536 P1128 035
Bank 1, mixture adaptation system too lean.
Any ideas would be greatly appreciated, since at this point I have absolutely no faith that this dealer has any idea what he's doing.

My son gets the same code (exactly) on his '00 GTI VR6....
Have you chipped? He has GIAC for VR6. Codes didn't start until he had miles on the chip.
FWIW: Corrective action printout for the GTI is:
1)Check oxygen sensor and oxygen sensor control before and after catalyst
2)Check fuel pressure regulator and residual pressure
3)Check mass airflow (MAF) sensor [same p/n for 180 TT & VR6]
4)Check intake system and vacuum lines for leaks
5)Check fuel injectors and EVAP cannister purge regulator valve output
6)Check air intake screen(if equipped) and air filter for blockage. [have you changed filter?]
7)Check exhaust system for leaks [do you have cat-back?]
8)Check Secondary Air Injection (AIR) system for leaks (if so equipped)
My $.02
