my check engine light keeps flickering on and itll do it for like 30 seconds to a minute then wont come on for a while....its not when im accelerating or anything cuz itll come on sometimes when im in neutral or slowing down...its totally random and it never stays on for more than like a half second but it will keep flashing on and off everysecond. does anyone know what i should check? or should i bring it in somewhere. i dont really have any money so i want to try not to get it serviced

If you have an earlier model, it's the 1.1 procedure. Later, the 1.3. http://www.unofficialbmw.com/repair_faqs/motronic.html

Sounds like your alternator is going. You could either test the voltage across the battery with a voltmeter, or just have a mechanic do it. It takes 2 minutes to do, they likely wouldn't charge you.
