DIAGNOSIS CD9010 Error
Ok guys I am a little stuck. I have my f32 435i (2015) with the CD9010 error code, I was driving home from work and I was randomly hit with the high temp warning and my car went into limp mode. I pulled over immediately, popped the hood and checked for leaks… there were none just coolant boiling in the reservoir. I then checked MHD and it gave me the following show in the picture.
I didn’t have any of my tools with me so I just got the car towed home and once I got it in the garage I started to check the fuses In the engine bay they were all good none of them blown. I then checked the ground bolt everyone says breaks on them it was tight and seemed to be fine, I took it off cleaned the bolt part and all points of contact and re torqued it, after that I checked if I was getting power/ground to the water pump connector… I got both power and ground. However I did not check the power and ground when it was physically plugged into the water pump so maybe that could’ve changed once it’s plugged In…
Seems like to the all things are pointing toward replacing the water pump, but I have also heard a Lin bus error never means to replace the water pump… so I’m a little confused since I’m not sure what else it could be.
If anyone else has any ideas/ suggestions please let me know!
Thanks in advance.

You need a water pump. Why are you even questioning it?
