Help! I changed out the coolant reservoir on my Son's 2014 528i xdrive and forgot to disconnect the battery. Before it said I needed to add coolant when it was full which has gone away after replacing. Now I have a hard U019F code for "Lost communication with engine coolant pump control module" and can't remove it. I don't want to send him back to College with a check engine light etc. Any DIY advice is appreciated. Several shop/scanners besides one at Dealer haven’t been able to turn it off.

Yeah my car is reading the same thing. I have no idea what to do. Did you figure this out?

Install ISTA and clear with it!

Check the water pump ground bolt
