To be honest, I am having all sorts of problems electrically. I have a radio that the sound just goes off for no reason and then comes back on when I return the next day. I have heater/blower problems. I have changed the large resistor under the dash with a new one, this makes the blower system work but it makes the fans run very slowly with the ignition off (but enough to kill the battery over a space of 24hrs). So I had to put the old one back in and have a manic windless blower system again. And the problem previously described. I love my X5, I love BM's (got a 2000 325 Ci Sport in black) but the problems I have with my X5 is killing me. Whatever I replace seems not to be the problem. Anyway, thanks for pointers Weasel.
