AWD Vehicles, Checking

Pay attention to the instructions on the test stand screen.

• Only check the brakes and the front and rear axle with the "engine off".
• Always switch off the engine during a brake inspection on the one-axle roller test stand to prevent generating drive from one axle to another.
• Only star the engine to create the necessary brake pressure for the brake inspection.
• Then switch off the engine again.

Test sequence:

• The operation takes place on a test stand.
• For vehicles with manual transmission engage idle.
• On vehicles with automatic or dual clutch transmission select the "N" gear.
• 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 (3.7 mph), otherwise the brakes may lock up due to the roller start-up delay (EDL regulation).
• Test stands approved by Audi meet these requirements.
