Description
OEM numbers 2205453532 and 0265109745 identify this as a genuine Mercedes-Benz ABS, ESP, PML and BAS control module for the W220 S-Class. Sourced from a running donor vehicle and tested prior to listing, this is genuine used OEM stock.
The ABS/ESP control module governs the full suite of active braking and stability functions on the W220 S-Class. It reads wheel speed sensor data from all four corners continuously, alongside yaw rate and lateral acceleration inputs. ABS modulates hydraulic brake pressure at each wheel independently to prevent lock-up during hard braking. ESP (Electronic Stability Programme) detects deviations from the driver’s intended trajectory using the yaw rate sensor and applies corrective braking to individual wheels while also modulating engine torque. BAS (Brake Assist System) amplifies braking pressure when emergency pedal application is detected, reducing stopping distances. PML (Pre-emptive Brake Pressure Modulation) pre-fills the brake circuit ahead of anticipated emergency stops, reducing ABS engagement delay. Communication with the hydraulic unit, engine ECU and instrument cluster occurs over the CAN bus.
Symptoms of a failing module include ABS, ESP or BAS warning lights on the instrument cluster, sudden loss of anti-lock braking, stability programme or traction control operation, fault codes stored in the ABS/ESP unit readable via Star Diagnosis, inconsistent or unexpected brake pedal response, or a permanently illuminated ESP/BAS OFF warning symbol.
This unit is in good used condition and is ready for fitment. Many similar OEM part numbers exist across the W220 S-Class range — always cross-reference the exact number printed on the module with your vehicle’s diagnostic scan result or chassis number before ordering. Professional installation is strongly recommended, and coding or adaptation with Mercedes-Benz Star Diagnosis equipment may be required before the module operates correctly in your vehicle. A 14-day return period applies to all orders.
Returns accepted only for genuine faults — faulty on arrival, not as described, or wrong part supplied — requested within 14 days, with all 3 anti-tamper stickers intact. No returns for change of mind, incorrect installation, coding/programming, or buyer compatibility errors; checking compatibility (OEM number, firmware, vehicle) is the buyer’s responsibility.
