Description
OEM numbers A1685451332 and 0265109619 identify this as a genuine Mercedes-Benz ABS, ESP and HBA control module compatible with the W210 E-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 vehicle’s 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, where fitted, reducing engine torque. HBA (Hydraulic Brake Assist) detects emergency braking intent from pedal application speed and rapidly boosts hydraulic pressure to the braking circuit, reducing stopping distances in critical situations. The module communicates with the hydraulic unit, engine ECU and instrument cluster over the CAN bus.
Common signs of failure include ABS, ESP or HBA-related warning lights illuminating on the instrument cluster, deactivation of anti-lock braking, electronic stability control or hydraulic brake assist functions, stored diagnostic fault codes readable via Star Diagnosis or a compatible OBD scanner, inconsistent brake pedal behaviour under hard stops, or the ESP 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 W210 E-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.
