Sorry I put my latest post under Flat battery dont know how to move it to this one.
Sounds really odd. It must drive you mad not knowing if your Z is locked all round or not.I have put a little 3 in one oil on key and in barrel but the action is very sluggish/delayed which it wasn't before battery went flat ?
My inside light works ok, but there is no lock on the filler flap only inside which is operated with a key.
At the moment drivers door works on its own but sometimes with the boot.If I lock the boot and the drivers door is un locked it will also lock.If I push the internal button down on passenger door it will lock drivers door, but if I lock the passenger door with a key it does not lock the drivers door. It all seems very strange to me and not logical.
