I might have one, but I'm in a different country. I'm curious what's wrong with the current one, as they rarely fail. Unlike their predecessor CEM-00/01 which is prone to water ingress.

The symptoms are the indicator relay clicks continuously, even when testing the board out of the car by applying 12V to the board. at the same time as this fault occuring the rear heater and door open light appeared on the dash.

The main reason that I believe it to be the CEM is that when running the output diagnostic check (using the jumper pin under the bonnet) the relay stopped clicking for the duration of the test,only to resume after the test was complete. I feel that it can only really be the CEM right?

besides the constant clicking, the indicators + hazards all work fine. battery is good too.
