Descriere
Numerele originale 0285458432 și 0265109503 identifică aceasta ca o piesă autentic 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 processing unit for the W220 S-Class active braking and stability systems. It reads wheel speed sensor signals from all four corners alongside yaw rate and lateral acceleration data. ABS modulates hydraulic pressure at individual corners to prevent wheel lock-up during hard braking. ESP (Electronic Stability Programme) compares actual vehicle yaw rate against the intended path derived from steering input and selectively applies braking to individual wheels — plus engine torque reduction — to keep the vehicle on its intended trajectory. BAS (Brake Assist System) boosts hydraulic pressure during detected emergency stops. PML (Pre-emptive Brake Pressure Modulation) pre-charges the hydraulic circuit ahead of emergency braking events to reduce ABS response lag and shorten stopping distances. The module communicates with the hydraulic unit, engine ECU and instrument cluster over the CAN bus.
Common failure symptoms include ABS, ESP or BAS warning lights illuminating on the instrument cluster, deactivation of anti-lock braking, electronic stability control or brake assist, fault codes logged in the ABS/ESP module readable via Star Diagnosis or a compatible scanner, irregular brake pedal behaviour under hard deceleration, or the ESP/BAS OFF indicator remaining continuously illuminated.
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.
Se acceptă returnări doar pentru defecte reale — defect la primire, neconform cu descrierea sau piesă greșită livrată — solicitate în termen de 14 zile, cu toate cele 3 etichete de securitate anti-manipulare intacte. Nu se acceptă returnări pentru schimbare de decizie, instalare incorectă, codare/programare sau erori de compatibilitate din partea cumpărătorului; verificarea compatibilității (număr OEM, firmware, vehicul) este responsabilitatea cumpărătorului.
