vw polo central locking problem

jharry32

I have a p reg polo 5 door, the central locking will open all doors when unlocked but will not lock any door apart from the lock the key. When locked the pump activates as you can hear it whirring but does not lock any of the doors any suggestions?

Take a look at the pump, in the right hand side in the boot. See if it has any damage to the pipe or wiring.

Test it by removing the pipe and locking and unlocking the doors and feeling the pressure....you may see if the pump needs replacing, simple job and probably quite cheap if you find a secondhand one.

Thanks for the suggesion, I tried the pump and it seems to have good pressure behind it as soon as i put my thumb over the end it stopped the pump. I've also tried to seal the end of the pipe but this has had no effect, all that seems left to me is that there must be a leak in one of the pipes somewhere although I think trying to find this will be a nightmare unless there is any other ideas I'm overlooking?
