Well, as the headline says, my TT is jerking when I am standing or driving at a traffic light. If I get on the gas then he drives like a 100 hp car, until then the full power is there again. This happens at irregular intervals. Does anyone know the problem??? So was already today for the 3rd time at the friendly. Nix in the fhelerspeicher, when the test drive is done everything is ok!!! BIn really despair, made the day before yesterday a change of oil, today BMC PlattenLuFi and übermo Rgen I’m going to put in new spark plugs. I bought the NGK PFR6Q. When the master saw this at Audi, he got almost a heart attack! “Don’t put in, only original Audi” he stammered… But on what they say, I don’t give anything more. I then called NGK, D&W and Wimmer extra. From all the green light for the spark plugs…
