8D0907389D VW AUDI A4 B5 Modulo ECU Controllo ABS 0265109463 – Originale Usato e Testato

Descrizione

I numeri originali 8D0907389D e 0265109463 identificano questo come originale Volkswagen ABS control module for vehicles built on the B5 platform, including the Audi A4 B5. Sourced from a running donor vehicle and tested prior to listing, this is genuine used OEM stock.

The ABS control module is the central processor for the anti-lock braking system on B5-platform models including Volkswagen Passat and Audi A4 B5 variants. It continuously reads wheel speed sensor data from all four corners and calculates the onset of wheel lock-up during braking. The module modulates hydraulic pressure at each affected wheel independently, pulsing the brake circuit to keep the tyre rolling and preserve directional control during emergency braking. On equipped variants the module may also support EDS (Electronic Differential Lock), applying targeted braking to a spinning driven wheel to redistribute torque to the wheel with traction. The unit interfaces with the hydraulic control unit and instrument cluster via the vehicle data bus.

Signs of a failing ABS module on these vehicles include an ABS warning light on the instrument cluster, loss of anti-lock braking or electronic differential lock functionality, fault codes stored in the ABS module retrievable via VCDS, ODIS or a compatible scanner, abnormal brake pedal pulsation during ABS engagement, or wheel lock-up during hard braking that the ABS would normally prevent.

This unit is in good used condition and is ready for fitment. Always verify the exact OEM part number against your specific vehicle’s reference before ordering — fitment can differ between Volkswagen and Audi A4 B5 applications despite the shared platform. Professional installation is strongly recommended, and the module may require adaptation or coding with VCDS or compatible software before it operates correctly. A 14-day return period applies to all orders.
