Mercedes W164 Steering Angle Sensor Module A1645458516

Mercedes W164 Steering Angle Sensor Module is a precision steering system component responsible for accurately reading the steering wheel position and transmitting the signal to the vehicle's electronic systems. As an original Mercedes component, it ensures operational consistency with factory electronics and stable performance of assistance and safety systems. This used module allows for a technically sound repair without the need for a costly replacement of the entire steering column assembly.

Function and role of the steering angle sensor module

The steering angle sensor module in the Mercedes W164 is responsible for the continuous measurement of the steering wheel position relative to the driving axis. Data from the sensor is used, among others, by:

• the Electronic Stability Program (ESP),
• traction control systems,
• power steering and steering assist logic during maneuvers,
• selected functions of advanced safety systems.

Thanks to this, a properly functioning module helps maintain predictable vehicle reactions to steering inputs and improves overall handling stability.

Compatibility and integration with Mercedes electronics

The Mercedes W164 Steering Angle Sensor Module is designed to work with the vehicle's factory electrical architecture and communication bus. This means:

• full integration with original body and chassis control units,
• proper communication with diagnostic systems,
• possibility of adaptation and calibration using standard service tools used for Mercedes vehicles.

Selecting an original module is particularly important in vehicles equipped with extensive active safety systems, where the accuracy of the steering angle reading has a direct impact on the operation of the electronics.

Product characteristics and condition

The offered item is a used module, which allows for an economical yet technically correct repair of the steering system in a Mercedes W164. Choosing an original component from dismantling is a solution that, in many cases, ensures better compatibility with the vehicle than replacements of unknown origin.

The steering angle sensor module is particularly useful in situations where errors related to ESP, traction control, or improper power steering operation occur after replacing steering column components. Replacing the module itself often allows for restoring the correct operation of systems without interfering with other subassemblies.

Benefits of using an original Mercedes module

Using an original steering angle sensor module in a Mercedes W164 brings a number of practical benefits:

• compatibility with factory electronics – no issues with bus communication or unsupported function errors,
• stable operating parameters – accurate reproduction of steering wheel movement in safety systems,
• possibility of diagnostics and adaptation using standard service procedures,
• optimal cost-to-repair ratio compared to replacing entire assemblies.

For workshops specializing in the Mercedes brand and users who care about maintaining the factory handling characteristics of the vehicle, choosing this solution is technically justified.
