A2115405945 Mercedes-Benz W211 ESP+PML ABS ECU Control Module 0265109538 – OEM Used & Tested

Description

OEM part numbers A2115405945 and 0265109538. This is a genuine used, tested Mercedes-Benz W211 E-Class ABS/ESP ECU control module with integrated AIRMATIC pneumatic level control interface (PML), removed from a donor vehicle and tested before dispatch.

The ABS/ESP control unit processes continuous inputs from all four wheel speed sensors, the yaw rate sensor and the lateral acceleration sensor. During hard braking it modulates brake hydraulic pressure via the ABS hydraulic unit to prevent individual wheels locking. The ESP programme compares actual vehicle yaw with driver steering intent and, when deviation is detected, selectively brakes individual wheels to restore the intended trajectory. The PML (Pneumatic Level) interface additionally communicates with the AIRMATIC suspension system, allowing the ABS/ESP unit to exchange data with ride height and suspension damping control. The module communicates with the engine ECU, instrument cluster, AIRMATIC control unit and hydraulic unit over the CAN bus.

ABS or ESP warning lamps on the instrument cluster, deactivation of anti-lock or stability control functions, suspension-related fault codes stored alongside ABS/ESP codes when AIRMATIC communication is interrupted, stored fault codes readable via Mercedes Star Diagnosis or compatible scan tool, or stability control remaining permanently disabled.

Good used condition. Verify the OEM number against your vehicle’s build data before ordering — this unit is specific to W211 vehicles equipped with the AIRMATIC pneumatic suspension system. Professional installation is recommended. Coding or adaptation using Mercedes Star Diagnosis is required after fitting. 14-day returns accepted on unmodified parts.
