Any way to confirm if my water pump went south?
My AP is giving me 2 codes stating my water pump is out. My battery completely died prior to the codes and I had to jump start the car. Is there any possibility a fuse was blown or something? My ECTs climb like crazy when data logging, but I had absolutely no issue prior to the car dying. I have 46k miles.
If not how expensive of a job is it to fix? |

Water pump is around $550 I think. And how ever much labor you can get it done for, I'm not sure. Mine was warranty

Mine did that also. I just added distiller water and A little coolant and it was good to go. I get a water pump code saying it's running a low power mode (75%). Which means it'll die soon. I bought a new water pump (which i got a killer deal on) and its sitting in my closet. Im just waiting til that one decides to go.
U can try trouble shooting before changing the pump but others will tell u to change the pump. I say if u have a good towing service wait till it completely fails and then change it. That's what I'm doing. Edit: are u on ur originak battery? If si the change battery And then see if it goes away... |

I'm planning on selling my car soon. Are my codes consistent with outright failure or is it just on it's way out?
Thanks for the help man. |

yeah, as soon as I got the low coolant warnings, I was okay for a couple of months, adding coolant and distilled water before it failed completely. Your codes are in line with the pump being on it's way out.

I read some threads where ppl had gotten a code for their pump and they changed the battery and the code was gone. We have an electrical pump and it wires directly to the battery. So if it's not getting the right amount of power it could throw a code or two. Bur if u had to jump start your car you would need a new battery anyways so why not change it and see if the code goes away. Make sure u register the new battery though with a bt tool.

I'm just a little freaked because when I was live data logging with my AP the ECT's were climbing to 240+. I really don't want to have to replace my heads |

I can turn my car on but it heats up pretty fast. I haven't checked my coolant levels yet. I am not car savvy enough to be able to discern the difference in sound between a functioning and non-fuctioning pump however...

Basically turn ignition on but not the car. Start the test with the bt tool on the water pump. And you'll hear a buzzing sound for like 7 seconds. If u don't hear a. Buzzing sound at all ur pump isn't working.
If your car is cool enough check the level of it. If its low add some distilled water to the minimum. Then tmr run to the BMW dealer ship and grab some BMW coolant. If u have another vehicle to drive take that one. |
