Hi having trouble with the central locking, have looked at the pump in the boot and cleaned it but only the front doors,boot and petrol flap lock.
If i manually lock the rear doors and then open again with the remote everything opens as it should. I take it that on one cycle the pump sucks to lock the doors and reverses to blow to unlock the door which seems right when you look at the pump when stripped down.
The strange thing is that if you give the door buttons a bit of assistance they seem to lock but have noticed that they require and awful lot more pressure to push the buttons down on the rear ones than on the front, any suggestions greatly appreciated.
Regards Mark

Then I think that you remove the door cards and spray the locks with PTFE on the inside moving parts, I think that it has all gone too stiff, thats all.

If you would like the info on removing the door cards please ask:D:D
