AWD Vehicles, Checking
Test on a one-axle roller test stand
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 of the engine again.
Test Sequence:
- The operation takes place on a test stand.
- For vehicles with manual transmission engage idle.
- On vehicles with an automatic or DSG transmission engage 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, otherwise the brakes may lock up due to the roller start-up delay (EDL regulation).
- Test stands approved by Audi meet these requirements.
