Nowhere near home. The battery warning light appears, the electrics start misbehaving, and within twenty minutes, you're on the hard shoulder, wondering what to do next. Modern BMW alternators are more complex than the ones fitted to cars twenty years ago. They're now integrated into the car's energy management system, controlled by the engine management unit, and in some cases are part of a belt-starter-generator setup on mild-hybrid models.

And when it does, the consequences can be swift and expensive. A working water pump keeps coolant circulating through the engine. When it stops, the engine overheats. When an engine overheats badly, you're looking at warped cylinder heads, blown head gaskets, and repair bills that can run into thousands.
