Hello, I would like to pay for my old car and finance a new car. However, my old car has a problem that after a short time (mostly on the highway) it starts to hammer and jerk. Strongly noticeable at the accelerator and strongly audible from the engine room / chassis (difficult to locate) I was already twice at a workshop and there was nothing found!. As there is thus no obvious damage here and not even a workshop is damaged. I don’t want to go into the fat cup because of fraudulently concealed deficiency or something like that :/ Many greetings
