Hello, I have the following problem at my Tiguan 5N (2009, 150 hp, 4-motion, 156000 km): From 2000 – 3000 revolutions during acceleration a clear jerking or stucking can be noticed. Over this speed and also below there is no problem. It also occurs in every gear – especially in the lower speed range when accelerating. No matter what weather and whether the engine is warm or cold. I have VCDS and the fault memory is empty. Tubes are so tight, Turbo is new (the stucco was already before). Maybe someone can give me tips on how to “test” with VCDS and above all which values are in the tolerance ranges. Thank you!
