first i would check the coolant level, and if low, then find and repair any leaks.

the coolant would not be circulating if the pump decided to go south, and a non-contact infra red thermometer would work great to check the temps.

iirc, there should be a bleeder on the thermostat housing. i believe all of the m30 engines are similar in this proceedure, so there should be lots of diy's online. pelican may even have a good link as well. here's one that i have glanced over and think is accurate to the proceedures) i have done on many, many different makes and models, not just bmw.

good luck,
