So I picked up a Xtool VAG401 for my 2000 a6 Quattro, car was running fine before I hooked it up just wanted to check the codes. Had codes for O2 sensors so I cleared in case old they were old codes not cleared. Took the car out for a drive and went to go up a pretty steep hill and could barely make it up the hill, so hooked up again and I get a different fault I’ve never seen before and have never had a problem with until this incident. Any advice would be great putting a picture of fault. Ok so file didn’t load so trying this instead. Fault is charge pressure control positive deviation.

it is a turbo model
