Hello i am running a single turbo 335 E93 with jb4 backend flash.
Few miles ago the navi dashboard shows all these erros:
-Driving stability
-Dbc Failure
-Flat tyre monitor failure
-Start assistant inactive
-Abs.

After a few miles these message dissapeared but they come back again.

I tried to read dme codes with jb4 mobile app, mhd app and bavarian technic cable, but nothing relative appeared, altough i tried at map 0.

In the past i took it for service at bmw dealer and he couldn't connect to the dme (I don't remember if i was on map 0)
I don't know if jb4 or mhd backend flash conflict with bmw program

2 Questions?

1) Because the dealer is 200kms away, is there a way to completely turn off the jb4 without removing all the harness?
I mean maybe disconnect the power supply or negative cable of jb4.
I ask incase that dealer cant read the dme in map 0.
Should i reflash bak to stock with mhd?

2) If i purchased protools app does it manage to read these specific codes?
Or it is the same with jb4 and mhd reading?
I know in the past bmw program have better capabilities to reading codes.

Thanks,
Sotiris
