I just purchased a used 2012 a4 6MT quattro with around 70K miles. Car is awesome. One little thing that annoys me is that the car doesn't beep while pressing the lock button. My panic button still works on the keyfob as well as the horn in the car. Any idea how to fix this to get the locking chirp/beep enabled? It drives me crazy because I have to look at the vehicle to confirm its locking.
