2011 F10 N63 BMW HVAC Aux water pump

Supahone · 03-13-2023, 05:18 PM

I have an 11 BMW F10 550xi N63 I know it has three water pumps, one for the engine, one for the turbos and one for the HVAC. When I tried to prime the system after changing the hvac valve control, I could hear that the electric pump was failing and grinding and not pushing any fluid. Thing is I can't find the location of that HVAC pump or source the right one. Any help or pictures would help.

So after some deep sleuthing I finally found the hvac water pump that primes the heater core. I initially thought it was the heater valves but it was this failing auxiliary water pump. Evidently the F10 550xi has four pumps. This particular one is under the driver side fender well.
