WARNING: This page does not describe the selected car, but rather 13 other vehicles, including the 2017 Audi SQ5, 2017 Audi Q5, 2016 Audi SQ5, 2016 Audi Q5, and 2015 Audi SQ5. However, it is still accessible from the selected car via links, so may be relevant.
ABS malfunctions do not affect the brake system and the booster. Conventional brake system stays operative even without ABS. A change in braking behavior should be checked. When the ABS warning lamp comes on the rear wheels can lock-up early when braking!
WARNING:
- 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.
The brake system is distributed diagonally. The vacuum brake servo unit boosts the brakes pneumatically.
Malfunction sources are reduced by direct connection of components named. The components are replaced instead of repaired.
- Before performing repair work on the anti-lock brake system, determine the cause of the malfunction using On-Board Diagnostics (OBD).
- When installing a new hydraulic control unit, the coding must be checked, refer to Vehicle Diagnostic Tester.
- Turn off the ignition and disconnect the battery ground cable.
- When working with brake fluid, observe the relevant safety precautions and notes.
- Bleed the brake system with the Brake Charger/Bleeder Unit VAS5234 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, ensure that a ABS-controlled brake test is performed at least once (pulsation must be felt at the brake pedal), refer to Vehicle Diagnostic Tester.
