AWD Vehicles, Checking
Test on a One-Axle Roller Test Stand
- Only check the brakes and the front and rear axle with the "ignition off".
- 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 (3.73 mph), otherwise the brakes may lock up due to the roller start-up delay (EDL regulation).
- Test stands approved by Audi meet these requirements.
