General notes on anti-lock braking system (ABS) Page 1 / 2 45-1 General notes on anti-lock braking system (ABS) The ABS brake system is divided diagonally. The servoassist is affected pneumatically by the vacuum brake servo unit. Models with ABS do not have a mechanical brake pressure regulator. A specially coordinated software program in the control module determines brake pressure allocation at the rear axle. Malfunctions of the ABS does not affect the brake system and the booster. Conventional brake system is not capable of ABS function. A change in braking behavior should be checked. When the ABS warning lamp comes on the rear wheels can lock-up early when braking! ABS allocation 1 - Hydraulic unit and control module 2 - Brake booster Control module - 1 - and hydraulic unit - 2 - comprise a single unit. Separation can only be performed when removed from vehicle. The hydraulic pump - 3-must not
General notes on anti-lock braking system (ABS) Page 2 / 2 be separated from the hydraulic unit. Separation is not possible on vehicles with ABS/EDL/ASR/ESP with hydraulic brake booster or hill assist.
Notes for repair work on Anti-lock Brake System Page 1 / 2 45-2 Notes for repair work on Anti-lock Brake System Before performing repairs to the ABS, determine the cause of the malfunction via "Guided Fault Finding". "Guided fault finding" is performed with On Board Diagnosis, using the vehicle diagnosis, testing and information system VAS 5051. Disconnect negative Ground (GND) cable from the battery with the ignition off. Carry out before welding with an electric welding tool see Additional Information Body Collision Repair - General Information. Before welding operations using an electric welding tool, disconnect the ABS control module. When working with brake fluid, observe relevant safety precautions and notes 47-4, Bleeding braking system. After work for which the brake system had to be opened, bleed the brake system with brake filler and bleeder unit VAS 5234 47-4, Bleeding braking system. During the final road test, ensure that a controlled brake test is performed at least once (pulsation must be felt at the brake pedal). Absolute cleanliness is required when working on the anti-lock brake system, it is not permitted to use any products which contain mineral oil, such as oils, greases etc. Thoroughly clean all unions and the adjacent areas before loosening, do not use aggressive cleaning agents such as brake cleaner, gasoline, thinners or similar.
Notes for repair work on Anti-lock Brake System Page 2 / 2 Place removed parts on a clean surface and cover. After separating the control module/hydraulic unit, use transport protection for valve body. Carefully cover or seal open components if repairs cannot be carried out immediately. (Sealing plugs, use repair kit 1 H0 698 311 A) Do not use fluffy cloths. Remove replacement parts from packaging immediately prior to installation. Only use genuine packed parts. When the system is open do not work with compressed air and do not move the vehicle. During painting operations, the electronic control module can be exposed to a max. temperature of 95 C for only a short period, and to a maximum of 85 C for longer periods (approx. 2 hours). Make sure that no brake fluid enters plug connectors.
