Hello, I have 2 problems with my 1.7 CDTI 74 kW (Z17DTH, Bj sometime in the summer of 2004). First problem: When I go on the gas the engine jerks. So the engine immediately responds to the gas and accelerates, but only a fraction of a second, then it jerks briefly (stops speeding up) and only then it starts to accelerate properly… (well, the problem wanted to describe as precisely as possible, if I had said the engine jerks briefly when accelerating would have worn off The same problem exists when I take my foot off the gas. It slows short, jerks short and delays further… (delay in the sense of the motor brake)… The less the gear, the more extreme the jerking… In case of stalling traffic in the first gear, you will be stupidly driving now since 22,000 km with this problem and the previous owner probably already the first 14,000 km The FOH could of course do nothing… Warranty has now expired… Second problem: In the case of rotary fences … I have heard the problem here more than once, but only with petrol engines… And the loud, rough noise only occurs suddenly at over 3000 rpm… It’s not the typical diesel nailing. And here too: The lower the gear, the worse… An idea of what causes it?? Thank you, Thomas
