Pete, I really dont know if this will work, but resetting the computer seems to cure all sorts of things. Funnily enough my offside rear door does that occasionally but as the child locks are off I can open it from the inside, presumably if the child locks are on that might be why you are completely stuck? Anyway I have a problem with the setting of the pinch point on the windows, i have to reset the computer first and I am hoping it also cures my intermittent door fault too. For resetting the computer I have been told by a citroen garage to disconnect the battery by one terminal, doesn't matter which, leave it disconnected for 10 mins then reconnect it, give it a couple of mins to go through all its checks then there's a further procedure for the windows, Anyway, if anyone tells me this is rubbish then i wont argue, its just an idea based on what i was told regarding my windows.
