this morning my 146 central locking seems to have got a mind of its own. when I open it via the key fob it keeps re-locking itself, i managed to lock myself out this morning getting something out of the boot while the keys were in the ignition - luckily I had my spare key! I've been trying to see whats happening and its erratic behaviour, as sometimes its goes through a cycle of locking and unlocking itself - all clunk - clunk - clunk. Sometimes it responds to the key fob, sometimes not! At the last attempt it wouldn't lock via the fob and I had to lock the drivers door using the key - which locks the driver and passenger door but not the rear doors! Really strange..
