Customer Question

I have a 2004 645ci; I have a couple fault codes and issues that I wonder if they are related: Fault code A375; A379. My right passenger door window will not lower when door opens so that it goes up when door closes (won't close completely). Also top will not go down. the A375 code is communication with air bag-ecu disturbed (error_1bus_connection failed) "static fault" same with blue tooth. Are these all related?

Hi there, does the "one touch" function of the window work both up and down? Thanks, JP

But the door won't close when it is all the way up. It needs to go down a little when it closes and then back up.
Also the other fault codes?
Customer: replied 2 years ago.
And are they all related, since the top won't go down either and it all happened at the same time

sorry I meant no on the one touch for the window going up and down. It works on the left but the passenger side
Expert:  JayPutelis replied 2 years ago.
So the one touch works or doesn't? What scan tool are you using?
Customer: replied 2 years ago.
