My 2.0 tdi 170 2007 , like quite a few others it seems, can be a bit rough idling, runs fine otherwise and is only rough now and then ( maybe about 30 - 40% of the time ) . I can see the rev counter bobbing up and down slightly. It makes me a bit concerned when stuck in traffic etc that it may cut out.
I've noticed a few posts on here and other forums.
Anyone here had this and been able to fix it ?
