Occasionally, the central locking triggers but doesnt seem to open the doors. What happens is I plip it, the alarm disarms, the indicators flash, it beeps, and the central locking makes a noise but the doors remain locked. However I can open them with the key and all the doors open as normal. Anyone come across this before? It only happens about 1 in 10 times.

anyone?

 

Mine did that, and it was the central locking timer in the passengers footwell. It had a load of water in it, which had corroded the PCB inside.
