I took my car to a hand car wash and the guy drying the vehicle off obviously had no idea when you attempt to open the trunk it was automatic , so he manually raised it all the way up while the motor was doing It. now it doesn't open at all.but it will close when the button is depressed.can someone please tell me if the motor has to be replaced or not. I know once I take it to the audi dealer I will be raped.... thanx in advance..
