Mein Auto: 2008 535i

I had the same issue and was hoping that was the case. Apparently there are 2 stages, more than likely if you are getting the overheat warning you need a new pump. I took a shot and gambled and lost. Replaced the Tstat and put it all back together, no luck had to take it back apart and replace water pump in the end. Good luck.

I need to know if you complete the automatic bleeding procedure for the electric water pump in a 2006 530i and you hear the pump activating and pausing then activating and pausing during the process and hear water moving, is it safe to say that the pump is working??

I am having an overheating message and rapid intermittent radiator fan operation (surging) and don't want to replace parts unnecessarily. If the pump operation seems normal than I will replace the Tstat and the temp sensor.
