i have a 2002 330xi and it has approximately 21,000 miles on it...all of a sudden today, for no apparent reason, the battery indicator lamp (the red one at the top middle of the dash, next to the yellow oil lamp) has been going on and off--staying on for 15 seconds, then off for 2, then on for 3, then off for 15....very sporadic...it's been doing it all day

this should not be happening should it?!
the car was always kept in the garage in the past and now it's in somewhat cold weather permanently (no more garage, i'm at school) but what the hell?!

please help, what can I do? what could be the possible cause? what's the best way to fix it (keeping in mind that the closest dealer is 80+ miles and I have exams and such)

thanks guys,
matt.

Check the voltage at the battery terminals with a DVOM. If it varies significantly when the light turns on, then off, you might have a voltage regulator/alternator problem.
