Does anyone have any problems closing the tailgate when pressing the close button on the underside of the tailgate? I dont have the comfort & sound pack. About 50% of the time, it goes all the way down, but doesn't fully latch and makes a beep sound. I've tried the reset procedure several times without success. Rang my Audi dealer and they said I had to wait 3 weeks as they were busy. Not a big deal, but find it embarrassing in a busy car park continually having to open & close the tailgate.
