6856980 BMW F01 F10 F25 AHV Electric Swivel Towbar Module – OEM Used & Tested

Açıklama

This BMW AHV swivel towbar control module is a genuine OEM electronic component for BMW F01, F10 and F25 models. Primary OEM number 6856980. It is designed to control the electric swiveling towbar, also known as the retractable tow hitch, by driving the motor that folds the ball neck out of the bumper and back into its hidden position, and by monitoring the position of the towbar.

Its job is to receive the extend and retract request from the switch, drive the electric motor, check the end positions and the locking of the ball neck and report the towbar status to the vehicle electronics, including the trailer socket function. A properly working AHV supports safe and reliable operation of the swivel towbar, correct locking of the ball neck and correct operation of the trailer systems in daily use.

Common signs of a faulty unit include a towbar that does not extend or retract, a ball neck that stops half way, a towbar warning in the instrument cluster, no reaction to the switch and stored fault codes for the towbar module. When the module fails, the ball neck may stay locked in the wrong position, so that a trailer cannot be attached or the towbar stays visible under the bumper. Worn contacts, moisture and mechanical resistance in the towbar mechanism are common causes of such faults.

This is a used original part, removed from a vehicle and tested before sale. Match the exact OEM number 6856980 before ordering. Professional installation is recommended, and coding of the module to the vehicle is carried out where applicable, so ask a BMW specialist before fitting.
