ABS, General Information

Models with ABS Bosch 5.7, the following version is installed:

• ABS/EDL/ASR/ESP

The ABS brake system is divided diagonally (two circuits). The vacuum brake servo unit boosts the brakes pneumatically

Malfunctions on the ABS influence the brake system and servo assist. A change in braking behavior should be checked. When the ABS warning lamp is lit up, the rear wheels may lock prematurely during braking!

For complaints, the hydraulic unit and control module must be replaced together.
