Açıklama
OEM references 1164094 and 5WK8437 identify this ABS ASC ES control module as a factory-original unit for the BMW E36 series. It is supplied as a genuine used, tested component.
The ABS module continuously monitors all four wheel speed sensors, detecting any wheel approaching lock-up during heavy braking. It signals the hydraulic control unit to modulate brake pressure at the affected corner, preventing lock-up and maintaining steering control. ASC (Automatic Stability Control) extends ABS by preventing wheel spin under acceleration via engine torque reduction and selective braking. The ES (Electronic Stability) variant adds yaw rate and lateral acceleration sensing to detect and correct oversteer and understeer by applying individual wheel braking.
ABS or ASC/ES warning lamp on dashboard, loss of anti-lock braking or traction control function, stored fault codes in the ABS/ASC module, unusual or inconsistent braking responses during emergency stops.
This unit is in good used condition and has been tested prior to listing. Always verify the OEM part number against your vehicle’s existing module before ordering. Professional installation is recommended, and coding or adaptation to your vehicle may be required after fitting. 14-day returns accepted.
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.
