Dear Forum, I’m driving a 2013 Jetta, 1.6 TDI BMT with just under 170,000km and have been having a somewhat unpleasant problem for some time now. Service and pickerl testing have only recently been done at VW, no defects found during the inspection. Only in the third gear, in the half-gas, at 40 – 45 km/h and about 1500 RPM the engine starts to jerk or stutter noticeably. It is a very strong jerking and it becomes, if you keep the half-gas, always stronger, until the whole vehicle practically hops away. EDIT: I should add that the jerking stops when the gas pedal or full-gas release stops immediately! I was already twice at VW because of this problem. You exchanged the AGR cooler the first time and at the second time two injection nozzles. The problem persists and tomorrow I drive for the third time to the workshop to denounce this problem. But before I do that, I thought that I could ask for answers here.
