Reset the Service Indicator (CBS)

Last updated: June 6, 2026

BMW’s Condition Based Servicing (CBS) on the BMW X1 (F48, 2015–2022) tracks each service item separately. When “Engine oil” or another item is due, you can reset it from the dashboard with the trip button — no garage tool needed. Do the work first; a CBS item only resets when it’s at 90% of its life or less.

Reset After the Service Only

Reset ‘Engine oil’ first if both oil and a vehicle check are due. The clock must be set correctly for CBS to log the reset.

How to Reset CBS on the X1 F48

1. Close all the doors.
2. Switch the ignition on without pressing any pedal — on keyless cars, press the start/stop button twice (don’t touch the brake).
3. Press and hold the trip-reset button on the cluster until the first service symbol appears.
4. Release, then press the button to select the item to reset; hold again when ‘RESET’ shows to confirm.
5. Repeat for each item you’ve serviced, then switch off.

You can also view the items under iDrive → Vehicle → Vehicle status → Service required.

If It Won’t Reset

• The item is above 90% life — CBS won’t let you reset it early.
• You didn’t confirm — hold the button again at the ‘RESET’ prompt.

Why won’t it let me reset?

A CBS item only resets once it’s at 90% of its life or below.

Does the clock matter?

Yes — CBS uses the clock; set it correctly (it stops if the battery was disconnected).
