A not very interesting update however its something I've been trying to sort on the Megane for some time.
There is a large oval grommet at the back if each sill. As this is where rust starts, but the area on my car is in good order, I thought it best to replace both crumbling grommets however they are impossible to find through normal channels.
I ended up having to go to Renner directly however the parts chap was really helpful. He emailed me an exploded grommet diagram of the Megane:
Its number 15 btw, a 2 piece effort.
Part number R77 93 974 272
Just sharing because it's hard to find and a fair few models use the same part. They keep the shite out the sill and all that.

Anyhow that's that, just keeping things in good order for now.
