- The ABS is generally maintenance-free.
- Testing, assembly, and repair work may only be performed by qualified personnel.
- By not observing the points described in the repair information, the system can be damaged and vehicle safety could be compromised.
- Before servicing the ABS, determine the cause of the damage using OBD.
- Disconnect the battery ground cable when the ignition is switched off.
- When handling brake fluid, observe the relevant safety precautions and notes. Refer to Brake Fluid General Information .
- Bleed the brake system using the Brake Charger/Bleeder Unit:VAS6860 for all work that requires opening the hydraulic system. High and low pressure testing should also be performed on the brake system.
- During the final road test, make sure that an ABS-controlled brake test is performed at least once (pulsation must be felt at the brake pedal).
