As the title already says, I also jerked off with my Audi 80 ABK (85kW, Built 93). I have read some reports, but no one exactly meets my problem. With me, the jerking always occurs at a gas position. If I want to speed up, then a short dropout occurs at the said gas position, afterwards it goes on without problems. A permanent jerking occurs only if I remain on the said gas position. If I give more or less gas, then there is no cracking n. With this gas position a pressure point of the accelerator pedal is also noticeable, but always, even when I didn’t have that jerking. Ask for help, since Audi dealers and “Gelber Engel” have no advice but to install spare parts.
