3.3 Test for vehicles with four-wheel drive
via a Haldex coupling
3.3.1 The brake test should be performed on
a single-axle roller dynamometer with
contra-rotating rollers for four-wheel
drive vehicles.
Contra-rotating means that the dynamometer rollers are driven
forwards on one side and backwards on the opposite side.
This prevents brake forces being transferred to the drive train.
The forward rotating wheel is measured during the test, which
means two brake tests per axle must be performed.
The maximum test speed must not exceed 6 km/h.
The test rigs authorised by Volkswagen fulfil these requirements.
3.3.2 If no test rig is available for four-wheel
drive vehicles, the brake test can also be
carried out on a standard single-axle
roller dynamometer as follows:
– Drive vehicle forwards onto the rollers.
– Switch engine off and wait for 2 seconds.
– Carry out front brake test.
– Start engine and wait for approx. 5 seconds until sufficient
vacuum has been built up.

– Drive vehicle forwards until rear wheels are positioned on rollers
– Switch engine off and wait for 2 seconds.
– Carry out rear brake test.
– Start engine and wait for approx. 5 seconds until sufficient vacuum has been built up.


Also das ist doch mal eine Aussage!
