Hi folks, I have just purchased a 2007 A6 2.0 TDI. As my query is more enginge related thought I would also post in here as well as A6 forum to see if anyone has had similar problem with an A4 2.0 TDi. Car seems fine apart from when starting from cold. After a couple of minutes the car is very shuddery / jerky but only between 1200 - 1800 rpm. Anything above this and its fine. If you stop it idles normally. Once the engine is warm the problem disappears. Almost feels like a misfire. It has been scanned with VCDS and no faults were detected. This is my first Audi and really happy with it other than this and was just wondering if anyone has had similar problems or recommendations to check?
