Description
OEM numbers 0245450732 and 0265109453 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 is the central processor for the W220 S-Class braking stability system. It continuously reads wheel speed data from all four sensors alongside yaw rate and lateral acceleration inputs. ABS prevents wheel lock-up during hard braking by modulating hydraulic pressure at individual corners. ESP (Electronic Stability Programme) detects oversteer and understeer through the yaw rate sensor and corrects trajectory by selectively braking individual wheels and reducing engine torque. BAS (Brake Assist System) detects emergency braking intent from pedal application speed and amplifies braking force. PML (Pre-emptive Brake Pressure Modulation) pre-charges the brake circuit to minimise ABS response delay, contributing to shorter overall stopping distances. The module communicates with the hydraulic unit, engine ECU and instrument cluster over the CAN bus.
Common signs of failure include ABS, ESP or BAS warning lights illuminating on the instrument cluster, deactivation of anti-lock braking, electronic stability control or traction control functions, stored diagnostic fault codes readable via Star Diagnosis or a compatible OBD scanner, erratic brake pedal feedback under hard stops, or the ESP/BAS OFF indicator remaining continuously active.
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.
