Brakes and Traction Control: Service Precautions

Brake test

Front-wheel drive vehicles
Perform brake test on a single-axle brake dynamometer.

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

All brake test equipment approved by Audi meets these requirements.

All-wheel drive vehicles
Test on a single-axle brake dynamometer for all-wheel drive 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, otherwise the EDL control can activate the brakes if the rollers start at different speeds.

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

All brake test equipment approved by Audi meets these requirements.
