Boot Lid - Relay?

Hi all,

My VRS boot unlock has stopped responding to either fob or button... arghh!!

If I hold unlock on the fob, the indicators flash (comfort blink) so the vehicle is receiving the command.

Fuse 31 is fine

I had a look at the boot lock mechanism and sure enough it was a jammed, so I would have assumed the fuse would have gone - but as above no (then greased up the mechanism so its all free again). Next thought was to bridge the electrical connector with a 501 5w bulb to see if any voltage is being applied - again none. So it looks like the power isnt getting sent down to the connector (both wires are showing as chassis grounded) - can anyone tell me if there is a relay I should be looking at (cant find relay diagram anywhere)?

VCDS says the car is happy, boot showing as locked when shut - open when open (inc light)... Help!
