Hi I recently purchased a A4 2.0 tdi S Line on a 55 plate. It has an uncomfortable idle that feels like a missfire. I can also slightly feel it when changing into second gear when the revs are a little too low and the engine is under load. Just feels like its holding back momentarily.
In my history documentation an Audi dealer has commented on this fault as being normal for the model and no fault found. Can anyone please comment on this as I cant believe this is normal as it is most uncomfortable. It is a BRE engine code if this helps and has 80k miles on it.

Many thnaks in advance!
