The has motor developed an annoying rattle. It comes from the rear and at first I thought that it was just something loose in the boot. Emptied said boot and drove around the block; rattle still there. Back on the driveway I finally narrowed down to the something in the boot door. After opening and shutting the boot door a few times I pinned it down. Something had come loose in the light cluster:

Manual was of no use as step 1 to replacing bulbs was 'open boot and remove trim' with a little diagram that unfortunately bore no likeness to the actual vehicle.

Couldn't work out how to get at it, certainly not without the risk of breaking something.
Took vehicle off to dealer. Mechanic take look, says it's a sealed unit and will have to replace the entire cluster. Also because it's classed as 'trim' it's not covered under warranty.
Will cost a few coins short of £100
