Hi, I bought my first Audi a few weeks ago. A6 2.0TDi 138bhp automatic. I noticed that csr at low RPMs (around 1300) struggles and had no power. Everything is fine around 2000 RPMs. Suggestions are it could be DMF which I think is not bcz it just been changed by the garage I bought it from or it could be EGR system and I've been told to blank it. Any thoughts on this one please?
