OMNIVALEA Sunroof Repair Kit Mercedes C-Class W205 57.5cm A2057800175

WHY SUNROOF MECHANISMS FAIL AND HOW THIS KIT SOLVES IT

The sliding sunroof on the W205 relies on thin guide rails and plastic clips that carry the glass panel through thousands of open-close cycles in a hot, dusty roof channel. Over time the rails wear and the clips fatigue, and the first symptoms are a panel that hesitates, jams halfway or clatters over bumps; left alone, the mechanism can distort and strain the motor. Mercedes supplies the fix as the complete sunroof component (OE A2057800175), an expensive answer to worn rails. This kit rebuilds the mechanism with new stainless steel rails and POM clips at a fraction of that cost.

WHAT TO CHECK BEFORE PURCHASING

This kit serves the W205 C-Class sunroof mechanism referenced by OE A2057800175, with rails measuring 57.5 cm. Measure your original rails before ordering, as related Mercedes models use a longer 62.5 cm rail that is not interchangeable, and compare the clip shape with the pieces shown in the product photos. This kit contains the rails and clips only; it does not include the glass panel, motor, cables or seals.

PROFESSIONAL INSTALLATION NOTES

Open the sunroof to its service position, remove the glass panel and release the headliner edge for access to the mechanism. Photograph the original rail and clip positions before disassembly, clean the tracks of old grease and debris, then fit the new rails with the supplied clips exactly as the originals sat. Lubricate the tracks with sunroof-appropriate grease, refit the glass and run the panel through several full cycles, checking alignment and flushness before final closing; re-initialise the sunroof motor if the panel loses its position memory after the repair.
