This is bleeding annoying. Two days ago, all of a sudden, when I get into the drivers seat after unlocking, all three doors lock again.

I noticed that the central locking has become VERY sensitive. When in the drivers seat and door shut I just have to tap the lock and all three locks shut (thats if they weren't shut in the first place)

Not easy to describe, but is this a known fault (with a fix)?? I have a UK MY99.

 

i m not sure is it will help, but try to check your central locking relay!!

 

I have exactly the same problem (MY94), how do I check the 'relay'?

 

I had this problem. If you've got an aftermarket alarm with central locking, these usually have a solenoid in the drivers door that operates the lock. These usually have some adjustment in them. You could always try posting in security as well.
