Oh Noooooooooooooo, not againsteve_earwig wrote:The door locks have microswitches in them so the locking ecu can tell if all the doors are shut properly, if not it just unlocks them again, which is just what yours is doing so it's possibly one of these microswitches up the creek. Or it's a wiring fault (given all your other issues this could be likely)

This is a continuing nightmare then

Last year, or was it the year before (

I took it round to our local car sparky who traced the problem to water in the drivers footwell shorting out a connection block. They chopped out all of those connection block, replaced them with waterproof ones and re-routed the wiring to keep these blocks out of any water that might collect there again.
I couldn't find any obvious route where water might be getting in, but remembered someone cleaning and polishing around rear light unit seals, possibly you Steve. So I did the same, every light, door seals, everywhere I could think of where there was a seal I could find, get to and clean. Last winter went well, no problems at all, but it seems likely it's all got damp and playing up again.
I'd better get stuck in and see where the water is collecting, dry it out and try to find where it's getting in now
