Hi.

If there is an air leak in the central locking system, do you have to check every single pipe and if so how?

Thanks

There are only half a dozen or so lines at the supply pump, and that is where you start checking. Check all of them.

If it is a really bad leak you will find it by just puting the hose in your mouth and sucking on it. Otherwise you can use a hand-held vacuum pump. They are about $25 at auto parts stores, and Autozone will even lend you one for free.
