BMW service and maintenance includes Engine Oil Service, Inspection 1 (or Service 1) and Inspection 2 (or Service 2). In this article, I'll explain what these terms mean when servicing your BMW Z4. Service intervals and maintenance items are based on mileage driven, elapsed time since the last service, fuel usage, engine temperature and number of engine starts. This service schedule is a good guideline for maintaining your BMW Z4.

When you switch the ignition ON or start the engine, the Service Indicator Display (SIA) in the lower half of the speedometer briefly displays the next service due with the message OIL SERVICE or INSPECTION. The distance remaining till the required service (in miles or kilometers) is also displayed. If the distance flashes and displays a minus sign in front, that means that the service interval has been exceeded.

Inspection 1 and Inspection 2 are specific service requirements depending on the mileage and service indicated in your instrument cluster. Service Inspections alternate: Inspection 1 comes first, followed by Inspection 2, then back to Inspection 1. Inspection 1 tasks are performed at every service; when you reach Inspection 2, you perform the tasks related to an Inspection 1 and the additional Inspection 2 tasks. These service intervals are performed when INSPECTION is displayed in the cluster. The first Inspection 1 is usually around 30,000 miles and the first Inspection 2 is around 60,000 miles.

Other items serviced at specific mileage intervals are, 60,000 miles spark plugs and 100,000 oxygen sensors. Every two years the brake fluid needs to be changed. Every four years the M-Mobility System sealant cartridge needs to be replaced.

When you switch the ignition ON or start the engine, the Service Indicator Display (SIA) in the lower half of the speedometer briefly displays the next service due with the message OIL SERVICE or INSPECTION.

To reset the indicator:
Turn off the ignition and place the vehicle in park or first gear (manual transmission). Set the parking brake. Shut the driver door.
Press and hold the Odometer / Trip Reset (green arrow) button and turn the ignition to the ON position at the same time. At this point, the display should read "test function." Release the Odometer / Trip Reset button.
Skip the test function by pressing the Odometer / Trip Reset button until the display reads OIL SERVICE or INSPECTION.
Release the button. Then press and hold the button again until the message center display reads RESET or RE.
RESET flashes for 5 seconds. Briefly press the Odometer / Trip Reset button during the flashing. This resets the display and shows the new status for 5 seconds.
