General information: Function:

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2003 Audi S8, 2003 Audi A8, 2002 Audi S8, 2002 Audi A8, and 2001 Audi S8. However, it is still accessible from the selected car via links, so may be relevant.

The Acoustic Parking System (APS) consists of:

Control module for parking aid -J446-
Right front parking aid sensor -G252-
Right front center parking aid sensor -G253-
Left front center parking aid sensor -G254-
Left front parking aid sensor -G255-
Left rear parking aid sensor -G203-
Left rear center parking aid sensor -G204-
Right rear center parking aid sensor -G205-
Right rear parking aid sensor -G206-
Front parking aid warning buzzer -H22-
Warning buzzer for parking -H15-
Switch for parking assistance with integrated function lamp (LED)

After switching ignition on, a self-test is performed that is completed in less than a second. The control module is now permanently in operation, but gap recognition is only activated once reverse gear is engaged or can be activated/deactivated with the switch for parking assistance.

When parking assistance is ready, a short signal is sounded (delay of one second for automatic vehicles due to P-D shift) and the function lamp in the switch lights up. If a malfunction is detected in the system, a constant signal sounds for 5 seconds and the function lamp in the switch for parking assistance blinks.

The pauses between chime impulses get shorter as the gap between vehicles gets smaller. For gaps under 25 cm, the chime becomes constant. (Volume and pitch (frequency) can be adapted using the VAG 1551. See Adaptation (function 10) ).

Special case: driving along a wall
