• a finish consistent with the styling line of the S-Class dashboard.

This allows the part to be used both for replacing a damaged panel and for restoring the full functionality of the parking system after interior wiring repairs.

• reliable button operation within the PDC system,

• easier diagnostics in case of potential faults, due to compliance with factory schematics.

This solution is particularly beneficial for repairs of premium vehicles, where maintaining original functionality and aesthetics is crucial for user comfort.
