The product has an assigned OEM part number and interchangeable numbers, which allows for precise verification of compatibility with a specific vehicle configuration in manufacturer catalogs or parts selection systems.

Product Characteristics and Condition

The roller blind motor guide rail comes from the Mercedes offer and is a dismantled, used item. This means the original construction and factory mounting points are preserved, which translates to correct fitting with existing trunk lid and rear panel elements.

The main advantages of this solution include:

• original geometry adapted to the W204 body,
• preserved factory mounting points and roller blind guidance,
• possibility of direct replacement of a damaged element without interfering with the lid's construction.

Benefits of Using an Original Roller Blind Guide Rail

Using an original guide rail with a drive in the Trunk Lid & Rear category allows for maintaining the proper operation of the roller blind and the aesthetics of the rear interior. A correctly selected component minimizes the risk of jamming, uneven rolling, or excessive play in the mechanism.

Choosing a used OEM component is also a sensible cost-effective solution while maintaining high quality of workmanship and compatibility with the factory roller blind system.
