This is a number read out through the key and determines what is due with the next oil change. Most M cars get spark plugs on the third oil change and resetting the counter at the 1200 mile service would cause the plugs to be due at 20,000 miles/2nd oil change and not 30,000 miles/third oil change.

Thank you for posting this info.
Now I wonder how many techs actually know the difference between resetting the 1200 miles service vs resetting the oil service.
