Hello together, I recently bought a Coupe Quattro Type89 with the rare 20V suction motor (170hp). To be honest, I am quite disappointed about it, because the start is clearly carrier than with the almost 35hp weaker 10V and even at high speeds you can hardly feel the power advantage. In addition, it sometimes jerks when accelerating and in idle mode the speed often falls into the basement during warm start, so that it almost runs out of itself. n, but it didn’t show a mistake. What do you think is the cause of these problems? And what do you generally think of this engine? Thank you for your help!
