Posting this from the side of the road as I limp home in my E90 330i. I can drive about 1/4 mile at a time and then the overheat light comes on and I pull over and wait for it to cool down enough to drive another 1/4 mile. There is coolant underneath the coolant reservoir. Any guesses? Water pump is my thought. We'll see when (if) I get home.

On the plus side, waiting for the car to cool down has given me time to read the internet and learn how to get in to the double secret BMW menus. So I can actually see my coolant temp now, which is nice.
