has anyone ever damaged the front of the vehicle? I have a 06 A4 Qtr and I was parked and when i backed up my bumper came off a bit. i never had that happened to me before in any of my previous cars. Because of that, the cover thats underneath the engine broke and I cant put it back on. Does it matter that i dont have a cover? does anyone know where i can get a cover other than audi?
