What does the service window in the iDrive supposed to do? When I click onto it, it lists oil check, brakes, etc., but always has the same mileage. There is no countdown to the next service, etc. (ie. the oil change lists 15000 miles, which it has since I bought the car. It still lists 15000, and there is over 16,000 mile on the car now.) The dealer says that's ok - that the car will let them know if there's a problem. Is that right?
I'm sorry this is a simple question, but this is my first BMW. Otherwise, the car's great!
