Condition, origin, and technical aspects

The offered motor comes from a Mercedes vehicle and is classified as a used part. This means it has been previously used but can still perform its function in the seat adjustment system, providing a practical alternative to new components. The location in the front – right side of the vehicle is important when selecting parts, so it is worth verifying compatibility with the seat configuration in your W204 unit before purchasing.
