Parking aid control unit J446
Introduction
The Audi TT Coupé ´07 is equipped for the first time with an acoustic parking system with ultrasonic sensors
as featured previously in other Audi models. A 4-channel rear acoustic parking system is available as optional
equipment.
The term "4-channel rear acoustic parking system" means that 4 acoustic parking sensors which monitor the
area behind the vehicle are integrated in the rear bumper cover.

The acoustic parking system control unit J446 is
a carry-over part from the Audi A3 ‘04. Both the
hardware and the software are identical.
The systems in the Audi TT Coupé ´07 and in the
Audi A3 ’04 (different installation positions of the
acoustic parking sensor in the rear bumper) are
differentiated by the software based on the control
unit coding.
