Good day,

Vehicle: 2020 X3M with iDrive6

The "BC" button on the steering column does nothing when I push it. Usually the dash displays total vehicle and trip milage. Sometimes after coding it will display MPG data or direction of travel for a short time but eventually it goes back to total vehicle and trip milage.

I have performed a full vehicle scan in ISTA and have no errors.

Is there any way for me to function test the "BC" button with ISTA?

Thanks

Jeff

The problem was a broken wire going to the BC button. I already had a thread asking for help with the specific problem.. so I updated the detail of my repair using ISTA here:

Great diagnosis! Man, ISTA beats those days when one had to look at schematics and use a VOA meter. Good job!

That wire looks cut. Was anyone in there previously? Any sharp metal edges on the column that would cut it?
