Self-Study Program

The onboard power supply control unit J519 known

from the Audi A6 ‘05 and A8 ‘03 is employed in the

Audi Q7.

Various additional functions were implemented for

use in the Audi Q7.

Installation location

The onboard power supply control unit J519 is

installed in the cockpit at the front left on the

control unit holder adjacent the steering column.

Variants

Compared to the new Audi A6 ‘05, only the Midline

and Highline variants are installed in the Audi Q7.

This is necessary because a rear window wiper is

always installed in the Audi Q7. In the Midline

variant or higher, the onboard power supply control

unit drives the windscreen and rear window washer

pump V59. The Highline variant is required in

combination with the electrical steering column

adjustment.
