Pay attention to the instructions on the test stand screen.

  • With AWD, Testing with a Controlled Opposite-Running One-Axle Roller Test Stand
  • "Opposite-running" means: the rollers on the one-axle roller test stand are rotated forward on one side and backward on the other side. During this test, the wheels of one axle are driven in opposite directions, to prevent delivering power to the other axle.
  • "Regulated" means: the speed of the test stand rollers must be regulated in such a way as to avoid any speed difference during the brake inspection. The transferring of a force to the rolling wheels in the roller set is prevented by the stationary wheel (outside of the roller set) via the drivetrain.
  • During testing, the wheel turning forward is measured, therefore two braking tests are necessary on each 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.
