0255454432 Mercedes W220 S-Class Steering Angle Sensor – OEM Used & Tested

Descrizione

This Mercedes-Benz steering angle sensor is a genuine OEM electronic component for the Mercedes W220 S-Class. Primary OEM number 0255454432. It is designed to measure the angle and the rotation speed of the steering wheel and to send these values over the vehicle network to the stability control system and other control units.

Its job is to tell the vehicle systems where the driver wants to go, so the ESP can compare the intended direction with the actual movement of the car and intervene when the vehicle starts to skid. The signal is also used by other systems that depend on steering position. A properly working steering angle sensor supports stable handling, accurate stability control, and correct operation of the related assistance systems.

Common signs of a faulty unit include ESP, ABS, or other warning lights in the instrument cluster, a stability system that switches off or intervenes at the wrong time, unstable handling in curves, a steering angle value that does not match the real position, and fault codes stored in the system memory. When the sensor delivers wrong data, the stability control may be limited or stop working.

This is a used original part, removed from a vehicle and tested before sale. Match the exact OEM number 0255454432 before ordering. Professional installation is recommended, and calibration or zero-point adjustment of the steering angle with a diagnostic tool is usually required where applicable, so confirm the fitment details of your vehicle before you buy.
