Mercedes R129 Memory Seat Switch Cover – L or R

This is a precision-engineered replacement for the memory seat switch cover on the Mercedes-Benz R129 SL-Class. The factory switch cover — OEM parts 1297273988 and 1297209370 — is one of the most-handled interior trim pieces on the R129, and it shows. It cracks at the clip points, fades, and the finish deteriorates from daily contact. We re-engineered this cover in ASA to restore clean switch aesthetics and a secure fit that holds permanently.

✅ AVAILABLE LEFT (DRIVER) & RIGHT (PASSENGER) IN BLACK, BEIGE & GREY: Six variants covering all R129 interior combinations. Order the side and colour that matches your car's specification.

The Engineering Edge

• ASA Construction (Color-Through): Moulded from engineering-grade ASA with colour running throughout the material. Daily contact and minor abrasion will not expose bare plastic — the same colour shows through at any depth.
• Reinforced Clip Geometry: The clip and tab positions are redesigned with increased engagement depth — the cover locks onto the seat switch assembly firmly and resists the working-loose failure mode that plagues factory units.
• Exact OEM Switch Interface: Every button aperture, surface profile, and mounting position is reverse-engineered from the original part. Switch function, tactile feel, and visual alignment are factory-correct on installation.
