Rough/Lumpy idle on A4 2.0tdi

[Camper67]

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!

my idle is fine but mine hold back slightly too,
got it checked and it was returned to me saying
that no faults recoreded,
doing my head in now cause I cant find a cure for it

Thanks interesting to know it is wider spread fault as others have said this is normal. I cant believe it is as who'd buy another if it was? Ive always had VW or Audi's and never had this before. Why is it these days if the diagnostic says no fault found the case is closed. Like you say does your head in. I will keep digging. Cheers!

Arh man sounds like youve had a right nightmare. Well mine is only a mild form of what you have or had there. Have you got on top of the problem now? You have given me food for thought though thanks very much mate and hope you are now sorted. Cheers!

Don't quote me but i have been looking on this site about the idle judder coz i have the same problem and what i found is that is just a characteristic something to do with the oil pump not being balanced so they all do it lol
