2006-2013 N52/N54 6-cylinder.

This was BMW's first electric water pump. Switching to electric offered many advantages - less wear and tear on belts, simplified the belt and pulley system, better fuel economy due to less parasitic drag, and cooling could come under electronic control.

BMW abandoned their mechanical water pump in the 3 series when they moved to the E90 generation in 2006. The electric pump is the only pump. A quick search reveals that all other typical cooling system components (i.e. thermostat) still exist, so even when the engine is warming up the coolant circulates.

Here are 5 signals that a BMW water pump failure is imminent: 1. Coolant Leaks. If you notice leaking liquid coming from the front part of your car, you should always pay attention to it, as it may be a symptom of problems yet-to-come. If the liquid is blue in color, it’s quite possible that you have a coolant leak.

The electric coolant pump wasn't running because there was no fuse for it so soon as I plugged that 40a in n cleared the codes it ran, im starting to think my misfire problem could be because of this because some fuses control the ignition coils and fuel injectors,so im going to post a picture of my fuse box and if anyone notices some fuses in the wrong spot or is missing one plz lmk.

Fuse 31 was ok, and so was all the others. Fuse 33 gave 12 volts to pin 1 on the water pump connector. I already had the correct voltage readings on all the plugs except for terminal 1. To help diagnose it I had to extend the ground wire so I could connect it to my old water pump. Then I did the bleed procure. The old pump worked plugged in.

BMW X5 Xdrive 35i N55 E70 with 75,000 miles. Car overheated, drove it home after engine cooled down. Ran ista+ on it and have no fault codes for electric water pump. I tried the self bleed system but it does not work. I do not see or hear water pump working.
