When are you due for maintenance?
The two factors that determine the appropriate maintenance service due for your vehicle are time and/or your service indicator. Time is the default but is secondary to your service indicator. In other words, if your service indicator is not requesting a maintenance service but it has been one year since your last maintenance service you should schedule a Low Mileage Oil Service based on time. If your service indicator is requesting a maintenance service, regardless of the time interval, you should schedule your maintenance service based on you service indicator. There are two forms of service indicators on BMWs. Both appear momentarily during vehicle startup on the instrument cluster. The first is a series of five green bars followed by one yellow bar and one red bar. If your vehicle has this type of indicator, service should be scheduled when you are down to the yellow bar. The second type of indicator is a numerical count down to your next required service. If your vehicle has this type of indicator service should be scheduled when you are down to 100 miles.
