@ Diesler I had a problem today. Driven 20 m backwards from the parking gap, after that normally continued……. From this time speed swings in the stationary gas. When switching down to stop then the corresponding jerk in the gearbox to the stand of the vehicle. That at every further traffic light…. After another 5 km, red traffic light again, construction site, car switched off, restarted, everything without speed swings, as if nothing had been! two times, in larger intervals (months). Strangely always after the reverse driving. Must say, however, that in my opinion the shutdown to stop and the starting is generally too “hard”. Turbos and gear oil change (ATF_055_055_A2) was done times at about 50000 km on Kulanz, now are about 70000 km on the clock. Ride rather restrained, unfortunately mostly short distances 10 to 20 km, rarely highway. kopi63
