Purpose and Function in the Steering System

The offered part, described in the title as Mercedes ML W164 Steering Angle Sensor Slip Ring Squib Stalk, is an integrated module mounted on the steering column in Mercedes ML W164 generation vehicles. It combines the functions of a steering angle sensor, an airbag slip ring, and a stalk assembly, enabling seamless operation of the steering system, active safety systems, and vehicle function controls from the steering wheel.

The steering angle sensor transmits information about the current steering wheel position to the control units, which is crucial for the proper functioning of systems such as stability control and advanced assistance functions. The integrated slip ring ensures a stable electrical connection to the driver's airbag, and the stalks allow for convenient control of selected vehicle functions without taking hands off the steering wheel.

Benefits of Using an Original Steering Column Module

Using a complete module from the Steering Columns group to replace a damaged part allows for the restoration of correct cooperation between all related systems without the need to match several separate parts. The original design ensures:

• accurate replication of the steering system's factory parameters,
• correct communication with the vehicle's electronics,
• stable connection of airbag and stalk circuits,
• mechanical compatibility with the steering column and interior trim.

This reduces the risk of errors in safety systems and problems with steering angle sensor calibration after installation.

Component Condition and Installation Aspects

The product is offered as a used original part, allowing for economical vehicle repair while maintaining compliance with the manufacturer's factory specifications. The module is designed for installation in place of the factory assembly on the steering column, using the original mounting points and vehicle electrical connectors.

When replacing, it is recommended to:

• adhere to safety procedures related to the airbag system,
• correctly set the sensor's neutral position relative to the steering column,
• perform adaptation or calibration of the steering angle sensor using an appropriate diagnostic tester, if required by the vehicle manufacturer.

Selection by Part Numbers and Vehicle Compatibility

The component has a dedicated OEM part number and related interchangeable numbers, which facilitates precise identification and selection for a specific Mercedes ML W164 version. When purchasing, it is advisable to compare the markings with the currently installed module or use the manufacturer's catalog to ensure full compatibility with the vehicle's equipment version and the installed steering column.
