How did this turn out in the end ? I MIGHT have found a solution to raise the static speed limiter again with VCDS, but no, I am not sure it will work so I wont try it with my own carIf no one has a car with a speed limiter set to a unbelivable low setting, then I will have to buy another ecu for my A3 and try it out.
Dealer reflashed the ECU and all was well...
