Interestingly, bmw scanner 1.4 doesn't show any errors in ZKE module.
I can try ISTA, but if ista doesn't show errors, then I doubt nt510/710 will.
The error only comes up when I start driving. I even tried scanning zke module *while* driving, and still no errors.
When I stop driving, I don't see the error anymore, and pressing the right button on the dashboard doesn't bring it up from memory.
Interestingly, my center console button doesn't work either right now. When I lock/unlock the vehicle from remote key, all doors lock and unlock, except the driver's door. I wonder if this has anything to do with the fact that I've disconnected the driver side door module for now (the one that controls windows and mirrors).

Door open fault
 

Door open not an error “more of a comment, really”.

But a good scanner will show which door switch is reporting open.

Lots of things won't work with driver master door module unplugged.

I think that was the issue. Everything fixed now.
All 4 doors are working properly and open from inside and outside. Let's see how long they will last lol

Central lock button working?

Yes, everything working now!
