Guys, I believe my car (05 E90 325i) might be running into the same issue.

I spot the 2E81 code.... cleared it and it showed up again after a trip.

Seems my pump is going. Weird enough though, the RPM did drop to 0 according to the record but I did not get any overheating warning (YELLOW or RED).

So I'm not sure if it is a sensor issue or the pump issue itself.

Having said that, according to OBD2 reading the coolant temperature is maintaining around 100-105 degC (not F) under daily drive. Is it normal?
