Hi I have a 2007A6 diesel recently had egr blank and new mass air flow as faults was coming up...car drives fine when accelerate slow but if I accelerate fast in second gear and above in jerks and ideas thanks 

Hi James

Hope your well, how long has this been going on for? could be a gear box fault but not 100% hopefully someone can help you better, or have a diagnostics on it to see if any other codes come up.

As Brad-B5 has said, a full diagnostic check would isolate the cause but also if the EGR plate doesn't have a small hole in it to allow a certain amount of gas through it can throw up faults.

Another thing worth trying is running a fuel treatment and intake cleaner through the engine to see if that sorts it out.

Let us know how you get on with it

Cheers  Trevor
