If you hear a long beep for a few seconds and the diode in the switch
starts flashing when you switch on the parking aid, or while the parking aid is activated, a system fault has occurred. Please have the fault corrected by an Audi dealer or qualified workshop.
Note
If the fault is not corrected before you switch off the ignition, it will only be indicated by the flashing diode in the
switch the next time you switch on the parking aid by engaging reverse gear.
