I had the same problem with my 146ti. Put post on here and main concensus was 'Door Solonoid'. I phond a few places, one being an Alfa specialist and from memory, had quotes around the £150-£200 mark I think ??
I went back to my local garage and they had a real good look, and noticed the drivers door hinge was loose, where the weld joint was cracking. So when the door was opened,it dropped ever so slightly, which set the central locking going on & off. You could lift the door up slightly when it was open. It was where the hinge attached to the car body, not onto the door.
So I took it to a car repair workshop/welder, he agreed it was prob the roblem and said if I left it with him for the day he could do it.
£50 later all fixed and no locking problems ;-)
Hope this helps ? ;-)
