I need to remove the rear number plate from my 2003 Allroad and fit a new one. It appears to be held to the tailgate with a couple of those small yellow plastic nuts & screws that are commonly used for holding registration plates. Getting to the screw head is easy enough (obviously!) but the nut appears to be somewhere inside the tailgate It looks as though I need to remove most of the boot trim to access the plastic nuts: is this really right? I'm loathe to damage the trim in the process and I don't yet have a Bentley manual, so can anybody please guide me in the right direction (perhaps based on painful experience!) of what should be a simple task?
