Lumpy idle when hot

[bokoboy]

Hi folks I have been reading about the lumpy idle threads but most seem to be when cold my 05 20 tdi bkd engine is suffering from this even when hot the needle is sitting steady at 800 revs but the car is not running smooth
it was serviced 4k ago new fuel oil and air filters ! Any suggestion welcome thanks

Get a VCDS scan as soon as possible. Most likely there is a sensor playing up, and therefore not fueling the engine properly. Other than that, look for injector problems on this forum. Good luck.

Are you sure the fuel filter was done, as its not run of the mill on a service.
