Pay attention to the instructions on the test stand screen.

Testing on a One-Axle Roller Test Stand for AWD Vehicles

• During this test, the wheels of one axle are driven in opposite directions, to prevent delivering power to the other axle.
• The test speed must not exceed 6 km/h (4 MPH), otherwise the brakes may lock up due to the roller start-up delay (EDL regulation).
• Test stands approved by Audi meet these requirements.
