The ASR hydraulic control unit is located on the left side of the engine compartment. For vehicles equipped with anti-theft radio, obtain the radio code. Switch the ignition OFF and disconnect the battery. Release the connector from the control module and disconnect it by lifting up. Connect a bleeder bottle to the bleeder screw on the left front brake caliper and open the bleeder screw. Insert a brake pedal depressor between the brake pedal and driver's seat, and depress the brake pedal by at least 60 mm (2.4 in). Do not remove the brake pedal depressor until all brake lines have been reconnected to the hydraulic control unit. Close the left front bleeder screw and protect the engine compartment from brake fluid spills. Disconnect the brake line connections at the hydraulic control unit and seal the brake lines and threaded holes with plugs from the repair kit. Remove the nuts on the hydraulic control unit bracket and then remove the hydraulic control unit. When installing, only remove sealing plugs on the new hydraulic control unit when the corresponding brake line is about to be installed, as removing them too early can cause brake fluid to escape, potentially leading to insufficient filling or inadequate bleeding of the unit. Bleed the brake system and reconnect the battery, entering the radio code.

Audi A6 ABS Control Module

The ABS Control Module on the Audi A6 controls the various anti-lock brake systems of the vehicle. This is done by monitoring the various wheel speeds and regulating hydraulic pressure. The control module helps the wheels turn and not lock up during hard stops. The ABS Control Module is the brain of the system. It processes the input from the wheel speed sensors to detect the first sign of lock-up. It then controls the valves to alter the brake pressure while the pump replenishes the hydraulic pressure. This feedback loop helps sustain propulsion so the driver can steer even under maximum braking. This also helps keep the Audi sedan stable during emergency maneuvers on pavement and a variety of slippery surfaces. The ABS Control Module in a single housing will work in conjunction with the electronic stability control and traction control features, which will brake the individual wheels or reduce throttle when the sensors detect understeer or wheel spin on the Audi models. These functionalities are possible due to the network of sensors on each wheel of the Audi A6, electronically controlled valves present inside the hydraulic unit, and the pump that restores pressure after every modulation cycle. As it performs self-diagnostics, the ABS Control Module is capable of identifying internal faults or sensor inconsistencies. Moreover, it can store information that supports a warning light activation when it is necessary to intervene in the vehicle's electronic system. Audi incorporates this element as one of the four main components of the anti-lock braking system along with the sensors, valves, and pump. Each assists in keeping the A6 in contact with the road so it does not skid or swerve when the brakes are applied.

Choose original equipment manufacturer ABS Control Module for great performance and strong durability. They use Audi's official craftsmanship and high-grade materials, and meet strict quality standards. Are you looking for quality ABS Control Module at a good price? Come to our online store.
