I bought a replacement harness which also did not repair the fault. The latch operates by giving it a 12v pulse from the cig lighter so it does work...just not getting a signal using the remote or unlock button. Is this the CEM at fault and if so how do I get it sorted? Can the CEM be reset?

A bad microswitch in the handle itself maybe? I had that issue once, replaced the switch and it worked again. Well, for a few months until the harness went.
