1. On some Peugeot 305 models, a sliding sunroof is a factory option. Mounting details of the hatch are shown in B / fig. 11.20.
2. Maintenance of the hatch is reduced to checking the condition and reliability of fastening of its moving parts. Lubricate the pads and guides with Kluber Proba PN 9730.67 grease from time to time.
3. If the sunroof starts rattling, check the moving parts for wear and loose fasteners. Loose pad fastenings can be fixed with a special sealing tape for plumbing work (fum tape). Check that the cable is taut when the hatch is closed.
4. If the knocking does not disappear, you should contact a specialist.
