golf central locking pump - Dubbz
Hi All,
Need some advice please =o)
How do i tell if the air pump on my 91 Mk2 golf is on it's last breath? sometime's it will unlock all door's and other time's it wont lock any except the driver's door?
It make's the pump noise but dosen't shut off for a fair while, but, if you squeez the pipe on the pump it shuts the pump off/up!! =o/ not looking to start throwing loads of money at the motor as wanting to trade in =o) and just spent £200 on having a new starter fitted =o/

Many thanks.

sounds like there is an airleak somewhere, obvious place would be in the trunking where the pipes enter the doors they are rubber and will go brittle with age

You can buy refurb kits for those pumps, or you could get a used one.

Use a MityVac on each section of pipe to check for leaks.
