Brakes and Traction Control: Service Precautions

General information
The wheels are driven by the test stand.

For test, place selector lever in driving position -N- for vehicles with automatic transmission.

Follow instructions issued by manufacturer of brake test equipment.

Note: Electronic brake control systems are inoperative when the ignition is switched off.

Vehicles with front-wheel drive
Perform brake test on a single-axle brake dynamometer.

Test speed must not exceed 6 km/h. If the rollers start at different speeds, the EDL control can activate the brakes.

The Audi-approved test stands meet these criteria.

All wheel drive (AWD) vehicles
Testing on a single-axle roller dynamometer for all wheel drive (AWD) vehicles:

The rollers drive the wheels of one axle in opposite directions to avoid transmitting torque to the other axle.

Test speed must not exceed 6 km/h. If the rollers start at different speeds, the EDL control can activate the brakes.

CAUTION: The Torsen differential will be seriously damaged if test speed exceeds 6 km/h.

The Audi-approved test stands meet these criteria.
