I have a small intermittent rattle that seems to be in the passenger side B post. I have looked at the forum and didn't spot anything on this area...but plenty on rattles! I have listened with the window (front and rear) open and closed and had useful passengers holding bits of trim to try to identify something loose but nothing has been found. I did have the rear window fittings sorted last service, it is not that. I am considering removing the covers on the B pillar to see what is behind (besides the seat belt fixings) but has someone done that or has a schematic as it seems a bit drastic. Turning up the radio does fix the problem.
