hmmmm...what does the Audi shop diagnostics say is wrong?

BTW, it hasn't been a total waste of time and money..the de-carbon cleaning is a good thing on the early 3.2's unless the car is always driven at higher rpm highway speeds. That diagnostic will show any obvious engine miss..did the shop run this and come up with changing the injectors, did they give you a copy of the tests they ran? You've spent a fair amount on this issue so you deserve some real answers.

I think that the ECM is the problem.
Need help with activation of the new ECM.
I have VAG COM 908.1
Thanks
