318i central locking not working

[nathan87]

Hello

Right, my drivers door lock won't lock but will unlock the door

And the central locking doesn't work

First check whether your horn still works. If not, fuse 27 has blown.

There are several things that can go wrong with the central locking:
- microswitch in the door can stop working
- muck/corrosion in the connector on the A-pillar (that takes the electrics into the door) can block electrical signals
- worst case, the central locking control unit could have packed up

Ahh, I'll check them things next time out at the car

Cheers mate

The Wiki is a good place to start:

Horn is on fuse #7 and nothing whatsoever to do with the central locking, which is fed by #27.
Look in the wiki for references to some red/black wires.

I shall have a look at that aswell in that case

I just read the book again, it says 'on board computer horn', except that 'horn' in on the next line...
...of course this doesn't help if you haven't got an OBC.

Turns out my central locking motor/mechanism isn't even in the door

Found a load of them in the boot hidden under the manual lol

Sounds like you may have broken my #1 rule! "Never buy a car from an idiot."

OR "a penniless loser!" as you told me when I had similar problems with my C/Locking
