I have a problem with my Golf 6 1.6 TDI, when the DPF regeneration is in progress and i blip the gas for a secon *in neutral* my revs dont just go back to normal but they jump few times from 1000 to 1300 and back and after that all good...Also i feel like the car is jumping in the second gear on low rpms *like jerking* plus i need to give it more gas to prevent it from stalling when starting in first gear... Anyone here had the similar problem? This doesnt happen every time but quiet random. No codes present.
