Why does the water pump activate even when the car is cold after locking the doors?
Hello friends, I hope you can guide me to find the problem!
Some time ago, the car did not start and I realized that the battery was completely dead! I replaced the battery and registered it. After 2 days, the battery was completely discharged again. No error codes found for low battery or anything related. I checked with ISTA+ and bimrmerlink. By chance, I noticed the sound of the water pump after locking the doors! Apparently, it doesn't matter if the engine is cold or hot, this happens. I changed the thermostat last year because I thought the engine was a bit hot. I will say that I have not received any errors or warnings for engine heat so far. I open the negative terminal of the battery every night so that my battery does not discharge, I hope you can guide me. I want to thank you in advance. BMW 320i XDrive 2014 91,000 Km |

It's a known problem with some BMW's. You'll need to continue disconnecting your battery until you get the water pump replaced.
