i only saved your instruments, i'll get that off the laptop tonight and sent it across.
IIRC the fault was something like "light timeout too long" and the heated mirrors (which at the moment aren't going to be your main concern)
not sure what the plug is.
the immobilser could stop it from starting, but i think that would flash up on the dash will immob active or something as i doubt you could bump it if the immob is active.
just thinking is it possible that the alternator got so wet it stopped working, that caused the car to run off the battery thus draining it?
running the car on idle isn't going to get that much charge into the battery, you really need to take it on a proper run, or get the battery on a charger if the battery is flat.
