WARNING: This page is about a different car, the 2024 Audi SQ7, 2024 Audi Q7, 2023 Audi SQ7, and 2023 Audi Q7. 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. The conventional brake system remains operative even without ABS. A change in braking behavior must be anticipated. When the ABS indicator lamp comes on, the rear wheels may lock prematurely when braking.
The ABS is 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 performing repair work on the ABS, determine the cause of the malfunction using On-Board Diagnostics (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 Bleeding Equipment:VAS6860 or 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, make sure that an ABS-controlled brake test is performed at least once (pulsation must be felt at the brake pedal).
