one afternoon when returning home, the engine wouldn't turn off, the dashboard stop, oil and battery light remained glowing slightly, even after the key was removed and the engine was deliberately stalled. At this stage, alarm and central locking are working perfectly. As i have a small amount of knowledge of vehicles, i diagnosed a key switch fault as the solonoid had a continuous supply of power. we replaced the key switch and it's still the same fault. we looked at our haynes manual for the fuse list, no remedy for this fault was listed, so i started to randomly remove relays and fuses to see what happened. fuse 15 killed the engine at this stage, we also found the alarm and the central locking was disabled as far as the key remote was concerned, although use of the key in the lock works the central locking perfectly. according to the haynes manual, the alarm control unit is fuse 26 (this does nothing). Fuse 15 should kill the central locking control unit, remote control unit, courtesy lights, boot light and electric aerial, although fuse 15 being out does not disable the central locking and my boot light still works.
WEIRD

PLEASE HELP

Lee, Did you ever sort the problem out?
I have a 306 doing the same thing as yours.

Regards,
Andy

306 normally has a very simple problem that sends all the electrics funny, its the earth from the battery to the gear box, comes loose at the gearbox end, its worth giving it a look at and a little tug, same thing has just happened on our lasses car!

The background dashboard lighting and interior light are not working on my 306 diesel. All fuses checked okay. All other electrics appear fine, no problems evident. Anyone any ideas?

I've just experienced the same symptoms with my peugeot 306 more or less. Car is in the garage right now, so good to know what the fix was for yours?

Will post their solution when I've paid the bill.
