Ok, engine started throwing this code. Repair shop said it had to be the turbo but my research shows that most others are experiencing a loss of power with this code. I have no power loss.

I did have the piston repair but that was 30K miles ago.

Anything else I should be looking at?

Did you ever figure this out? I have same problem in my car

I had this and it was the dreaded wastegate play on the turbo. There is a temp fix but I elected for a new turbo.

what is the temporary fix? I had this code 100 miles ago and dealer replaces wastegate valve and after 100 miles it came back again

I beleive it is a modification to the arm. Search on the Audizine B8 forum. It has been discussed a lot over there.
