Just to add to Gripped's posts, i too bought a replacement central locking relay from Bongospares. It arrived today very quickly and fixed the problem instantly, so big thanks all round. Only downside is i was so certain that intermittent behaviour last Autumn was down to the wiring loom that i paid a lot of dosh for a new one

. Still, on the bright side, i would probably have needed one at some point anyway
