I have a rattle/squeek from the parcel shelf, i recall a thred about this and replacing the pins but i can't find it? Does anyone have a link to it or know what part numbers need replaced to stop it?

I suppose I could just answer with - Yes

In a search, put +shelf +pins and it returns threads that contain both words

On the subject of parcel shelves. Does anyone have any suggestions for cleaning a light coloured one which is showing general dirt and marks ?

Pressure washer

Seriously - not too close, but I regularly wash mine down with a Karcher and leave it in the sun to dry.

I’d second the pressure washer approach. Amazed how different mine looked post wash. I had a few stubborn marks that I pre-treated with Autoglym interior shampoo (neat), then a light blast over with pressure washer until all suds had gone. Leave outside to dry. L460 460e PHEV AB. Belgravia green.
