04 1.0 Central Locking Problems - JimC
Having locked the car either with the key or the remote, both doors and boot are secure.
However, after about 3 minutes, the car then repeatedly tries to lock itself - you can hear the solenoid clicking in both front doors every two or three seconds. This continues until the car is unlocked - so many hours if left.....

Any thoughts on what might be causing this?

I've wondered about sticking lock mechanism, or possibly the convenience control unit (don't know whether this car has one - my old Seat Toledo did and I had CL problems with that car also).

Thanks
