What this part does

The inner sill trim mounts along the bottom edge of the rear door frame interior, bridging the gap between the floor carpet and the door weatherstripping. It protects the painted threshold from footwear damage during entry and exit while securing the edges of the interior floor covering. On M Package vehicles, this panel typically features specific aluminum inlays or M-branded decorative elements that match the interior aesthetic. When this trim cracks or loses its mounting tabs, it exposes the wiring harnesses routed along the floorboard channel and can allow moisture or debris to reach the carpet backing.

Before you order

• Confirm whether your specific replacement requires the driver (left) or passenger (right) side, as the rear inner sill profiles are asymmetrical and cannot be swapped.
• Match the equipment level to the vehicle it came from. M Package trims have different cosmetic inlays compared to base or Executive Lounge variants.
• If your factory sills are illuminated, verify that this standard M Package trim meets your needs, as it may lack the required ambient lighting ribbons or wiring connectors.
• Before installation, carefully extract any broken plastic retaining clips from your vehicle's metal threshold slots to ensure the replacement panel sits completely flush.
