Hello forum, I drive a Seat Alhambra, 1.9 TDI pump nozzle, 2004 with 75,000km. For a few weeks I noticed when driving in the speed range of 1500-2000 tours that my car is jerking. The whole thing is independent of the speed and gear, the speed makes up. If you exceed the 2000 tours, the jerking is over. Can someone give me a tip what that can be? I have heard about a two-mass swing wheel? Can it be that? What symptoms would it have to occur if this is broken? Are there any culling rules with a four-year-old car? Who already has experience with such repairs. Maybe it’s also something else, but what can it be. If you get hot gas, then you don’t really burn it. But I can’t always give a sharp gas. Thanks for every hint. haprisi
