BMW X3 Service & Repair Manual: Maintenance service reminder reset - procedure 4

NOTE: On some models an appropriate scan tool may be used to reset CBS service schedules. By using suitable diagnostic equipment connected to the vehicle diagnostic connector it is possible to reset CBS service schedules at any time.

By selecting the `CBS' option, the diagnostic equipment will gather information regarding the current state of CBS items from their relevant modules on the CAN network.

Models using a Condition Based Service (CBS) service interval system, which displays a Service Need Display (SND). When ignition is on, Service Need Display appears under the speedometer in the instrument cluster for 10 seconds in the place where the fuel tank level is normally displayed. The first line corresponds to the mileage dependent service items. It specifies the mileage when the next service is due.

If the mileage is exceeded (service overdue), it appears with a minus sign. The second line corresponds to the time dependent service items and is displayed by a clock symbol. It specifies the weeks/months/years when the next service is due. If the service is overdue, it appears with a minus sign. The actual service item (with additional information) can be viewed in the control display.

Service reset is accomplished using instrument cluster:

1. Insert key into ignition.

2. Press ignition start/stop button without depressing the clutch or brake, and wait for the service reminder to dissapear.

3. Immediately after the service reminder indicator goes out, press and hold the odometer reset button or stalk. After 3 secs a warning triangle will appear, keep the odometer button pressed and after another 2-3 secs an oil can will appear.

NOTE: If the odometer button is pressed too long (10 secs in total), German writing will appear (giving the software level/ can bus etc. of the vehicle).

This indicates that you've overshot the reset procedure and you need to re-start from the beginning.

4. The service menu should now be displayed. Use the button (twist if the switch is a stalk - or if a button, tap repeatedly) to scroll up/down through the various service items.

NOTE: On newer models, it may be the rocker/toggle switch on the turn indicator lever that is used to scroll up/down through the various service items.

5. When the item to be reset is showing, press the BC button on end of turn indicator lever. "Reset" should now appear in the display. Press in and hold the BC button for 2-3 secs and a whirling clock icon will be displayed. The reset procedure for the selected service item is done.

6. Scroll up/down to select another item (as in step 4), or press the ignition start/stop button to exit.

NOTE: Residual wear or remaining time are specified (possibly with a minus sign). The "1" symbol means that you can reset service operation (early production vehicles may show an "F"), while a "0" indicates it is not resettable (the first 20 percent of the service interval is also protected against accidental reset).
