the are probably legally bound to replace it with a new one. Insist on seeing it before they fit it, try to see the serial number. What's the point of a brand new car with a second hand transmission???I recently took delivery of a factory ordered 2020 Macan S. The PDK transmission failed within two days of ownership and ~120 miles on the odometer.. I am being told by the service department that they will replace it with a rebuilt transmission. Does anyone know anything about the rebuilt transmissions? Considering the car is brand new, I think they should replace it with a new transmission or give me an extended warranty. I have never been in a situation like this so not sure what is reasonable to ask for. It certainly is very disheartening to have the car break down so quikly.
