Hello everybody!!!!!!!!!! As at the beginning of every autumn my car makes me again problems 🙁 the following problem: now that it has cooled down strongly outside, it starts to jerk strongly at “low” speed!!! My car: Audi 80 B4, 90 HP TDI, Limo, BJ 94, 270 000 km The whole looks like this: zb:. off to work – highway – you drive with relatively cold engine on the highway with heavy traffic – cozy with 110 km/h – about 2200 tours on the 5th aisle there and then want to get some schleuni because the traffic lights up and then it starts to bump extremely strongly or jerk what does not stop at all until you switch down to the 4th gear, which then naturally has to follow increased speed (approx. 2500 to 3000 tours)!! Then everything is ok again!!! What still goes on is that you just push the gas pedal completely through to the stop, then it also does not start to jerk or just short!!!! The whole thing I noticed already in the summer with cold engine, abe r by far not so strong and so long time!!!! with warm motor it almost does not come to the error!!! only very rarely and then almost not noticeable!! First I had to borrow the turbo in suspicion because the only at about 1500 to 2000 tours (I did not exactly look) starts (low speed), but as after longer observation comes out the jerking even if the turbo has already used!!!! It definitely rips the gear lever back and forth and the whole car look It’s like crazy!!!! It’s almost just going down and turning up and then up!!! Of course, the whole thing doesn’t just happen on the highway – even in the local area if you want to ride a small mountain with 50 kmh with the 3rd gear – you have relatively little speed again – it starts to bump and jerk!!!!! especially with a diesel where you actually have a lot of power at low speed and of course, that’s a lot high. ervige matter!!! can one with this error a mechanical error – drive shaft or so exclude?????? I would rather tap motor control – air mass meter or so or diesel injection!!!!! what would you say?????? Please thank you for the infos!!!!!!
