Ok guys I'm new to the mini world here I have a 2003 mini s and when I shut it off the dash lights stay on tail lights stay on wipers run constantly with key out I have noticed while driving the positive bat cable gets really hot and will burn you after long drives I have to disconnect the batt every night because of this issue I have narrowed it down to when I pull the driver footwell fuse box and look at the back of it top right plug c582 its black when i unplug it everything stops and goes out mind you theres no key in the car at all and when i plug it back in i hear a relay sound like inside the fuse box its self click and it all comes back on any one have any ideas it's very annoying thanks for your info

 

Similar problems, no solutions for a 2006 S R52; was fiddling with engine compartment fuse box to see if I could get to relay for failed (again) power steering pump; thought I had disconnected battery, apparently not. Battery cable to fuse box sparked when reconnected, and now wipers run constantly, even with key out of the ignition. Oh, and never did get to the underside of fuse box to see larger fuses for pump.
