Its a BMW thing for sure, my friend with a 340i just messaged me and said it just disappeared from the settings in his car. even though it could still very well be due to the new iOS.
Don't have an A91 edition, but I forget I have a HUD 98% of the time. Just so used to looking down for speed. Fully agree that it would be way nicer if it had a tach/gear position indicator.
No it doesn't, had to get a delete plug from BMW that eliminates the code, was like 25 bucks.
Just the MHD OTS stage 2 tune from the app, going to get it pro tuned eventually.
