When selecting and installing, pay attention to:

• compatibility with the vehicle platform (body series and generation),
• correct connection to the wiring harness,
• the necessity of potential adaptation or programming in the vehicle, according to the service procedure.

Product Condition and Service Application

The offered module comes from the group of used ignition accessories, allowing for economical repair of the system while maintaining the original design. This type of part is particularly useful in workshops specializing in Mercedes electronics and for vehicles where replacing the entire ignition switch assembly would be cost-prohibitive.
