Fuse #27

[offabroadway]

Hey everyone. So, looking for the gremlins in my car today. There are a few electronic ones, and they cheese me off sometimes. My parking brake light not coming on when the brake is on, for example. But what I couldn't understand is why the clock in a BMW wouldn't keep time, or show up at all, and why the central locks wouldn't work.

So I'm snooping about the engine and figuring out the approach to removing the ICV valve and cleaning it out, and I notice the fuse block. 27 is missing. I coud've sworn a fuse was supposed to be there. I go look in the manual and sure enough:

27 = 30A Central locking system, door lock heating, anti theft protection, OBC.

WTF?

If the on board computer isn't connected (I have the clock instead of the computer) that would be why my clock is out. Central locks too. Didn't even know I had door lock heating. And what constitutes the anti theft protection? Did some of these cars come without the central locking? So confused.

(And by the way, any ideas as to the parking brake light on the dash? All of those lights seem to work intermittently)... EDIT: Fuse 21 seems to be responsible for a lot of things, including the clock and various warning gongs. The interior lights are working, but the gongs are not. Why oh why?

door lock heating is when you pull and hold the outside door handle it will heat up the lock.
put your key in your drivers door lock and turn it 90degrees and pull it out while its at the 90degree position. this will double lock all your locks and activate the factory alarm. the locks, even when the windows are broken in, cannot be opened from inside or outside the car, without again using the key in the drivers side door lock.
