Hi all

Yesterday, all of a sudden, my front passenger door failed to lock with the central locking. I noticed it as I have the auto close feature enabled and everytime I accelerated from stop it attempted to lock.
On exiting the car and locking, I was able to open the door (obvious security issue, albeit the alarm sounded)
However, After the car had rested for five or so minutes the door locked appropriately.

Any ideas / anyone seen this before?
