Application and Function in the Vehicle

The presented control module is intended for installation in the front – right side of the vehicle, in Mercedes models from the W176 and W246 series. It is responsible for managing the operation of electrical systems in the front right door, cooperating with the body's wiring harness and other comfort modules.

Thanks to its factory electronic architecture, the module integrates with the vehicle's communication bus, enabling the correct operation of functions assigned to the front passenger door. Using an original control module from the same family ensures parameter consistency and predictable system behavior.

Benefits of Using an Original Door Module

Choosing an original electronic control module for the front right door allows you to maintain compatibility with the vehicle's factory configuration. In practice, this means:

• correct cooperation with the existing body electrical system,
• preservation of the operating logic for door-specific comfort and safety systems,
• easier diagnostics using standard service tools,
• reduced risk of communication problems between modules.

A component from the Electronic Control Modules and Controllers category of this type is particularly important in modern Mercedes designs, where most body functions are managed digitally.

Product Characteristics and Installation

The offered control module belongs to the group of dedicated door modules, designed specifically for the W176 and W246 platforms. The vehicle placement specified as front, right facilitates the selection of the correct component when comparing it with the currently installed module.

The product is marked as used, which in practice means it comes from a disassembly and has been verified for its suitability for further operation. This type of solution is often chosen as an economical alternative to new components, while maintaining the original manufacturer's specifications.

Selection by Part Numbers and Compatibility

The module has an assigned OEM part number and related interchangeable numbers, which allows for precise identification and matching to a specific vehicle configuration. When selecting, it is recommended to compare the markings with the currently installed component or verify by VIN number in the Mercedes catalog to ensure full hardware and software compatibility.
