Mine did this when I disconnected my door loom, I believe it's because the central locking pump works on a vacuum. Sucking the locks down if you will, so you may have a leak in one of the door shuts or your boot pump may have occurred a loose connection. Check the boot and doors but it should be a cheap fix dw!

oh thanks bud, i was thinking great thats all i need!!! i will have a look tomorrow when its light, cheers

Could be as simple as your drivers side door loom not being properly connected. But be careful there hard to get apart and put back properly lol..!

Could be the pump has failed too? It lives in the boot.

If messing with the door doesn't sort it, it might be worth swapping out the pump. Not sure if a fault code scan will show anything up? (Can't hurt doing on a new car anyway, check there's nothing hiding.)

My mates car has similar problems. She has to lock the car with the key. I checked out the central locking pump, an there was major corrosion where the loom plugs in. Was bright blue. Hopefully tho for you itll be the simple fix of what craig suggested. Second hand CLPs are about £50ish so nothing toooo major.

And she also has a problem with her window switches! I've plugged my window switches into her car and they worked fine. So if you're sure everything is plugged in properly, it may just be a case of having to buy some new switches.

Rich has a CLP for sale for a lot cheaper than £50 !

He also has the door microswitches that control it.

TBH though, you've got a leaky pipe, it blows air to unlock, it sucks and creates a vaccum to unlock, just listen for a blowing noise and start ripping things out till you find it.

Door switches are a common problem, if you're talking about windows?

thing is sometimes it works with the keyfob and other times i have to lock it by putting the key in the door?? bizzare.... is it something to do with the fact that the drivers side window control switch doesnt work? it doest work the central locking or windows..

Pop your passenger window switch and see if that works in your drivers side, if that works then it's just a switch you need.

My central locking stopped working and all I could hear was a hissing noise, it turned out to be the rubber onthe petrol cap that was causing the problem, took an age to find the problem.

Maybe it's me but I don't understand " the rubber onthe petrol cap that was causing the problem"

The rubber gasket around the locking bar which is connected to the central locking

cheers for the help everyone, i sourced another pump from a breakers over the weekend and its still doing the same thing so tomorrow im going to pull the doors apart and check for leaks..

as for the window prob it was just the switch..

Rich has a set of switches for sale.

How much for drivers rich ?. If this guy doesn't have them.
