If you play BMW a lot, you've probably had to bleed the cooling system. The plastic drain plug wears out over time and breaks in the cistern. Heat a small flat-blade screwdriver and heat it just enough to melt the broken piece still stuck in the reservoir. Just push and don't twist, min. When it's cool you can unscrew the old one and replace it. Do yourself a favor and replace it with this one BEFORE it happens.
