Hello Audianer, actually wanted to write it before, but nu is the end with Funny : When I slowly gas or slow down with my A4 2.5TDI 163PS 6Gang MJ2004 between 1500 and 2200 tours (so in the city traffic wants to flow along, keep speed) he reacts rather unpleasantly to the gas commands…either he wants to jump off or he starts to jerk – whether engine is warm or cold. Oh yes, I have the impression that he is worse under full load. Yes, I’m a “sensitive” driver – whatever that means 🙂 Many thanks for your tips, Thomas.
