Neither of these worked. I don't have the up/down scroller on my stalk. Also, my stalk has two buttons - Check and BC.
I ran to the dealer and the tech showed me how to reset it. With my E60, everything is done from the odometer trip button. Press and hold to get into the service menu. Press to scroll through the service options. Press and hold to reset whatever it is you need.
The tech said there are different ways to reset certain cars. They didn't charge me so I'm happy. Lol
