Here we are the end of day two with my TT in the shop (20k service, fix cell antennae ripped out at car wash, spoiler add on, and power loss above 4K rpms).
Service guy claims that after spending hours on the phone with Audi techs, they have isolated the power loss problem down to 3 different valves that went bad. I asked which valves, to which the service guy said "I dunno". I asked him if one was the diverter valve...maybe a -G part. To which he answered "yes".
Anybody got any idea what the other two valves are?
Furthermore, service was unable to tell me at this time what caused the failures, and if I need to be worried about them in the future.
Good news is that they should have my car done tomorrow, and they are covering all three days of the loaner car costs. At the very least, i can say that my Audi dealer is very customer service oriented.
