Hi,

My doors will sometimes keep locking and unlocking many times as I drive along, also they will lock randomly even when engine off.........

 

What is the most likely cause/remedy?

Check out your wiring between the a pillar and door. There is also a procedure on here somewhere about opening the door and the courtesy light being on to eliminate another fault. Have a peruse. I did for my daughters fabia and found the snapped wire in a couple of minutes.

Just a quick update on this, not had this problem happen again since I fixed the rear door leak into rear foot-well.......!!
