Oil Service is one part, or area of BMW's Conditioned Based Servicing or CBS.
BMW/Mini currently use this system to determine whether your vehicle is due for a service. CBS is a service schedule first introduced with the BMW 7 series (E65).
CBS is divided up into specific areas:
- Oil service
- Microfilter
- Spark plugs
- Diesel Particulate Filter (DPF)
- MOT
- Vehicle check
- Break fluid change
- Front brakes
- Rear brakes
An indicator/light will come on your dashboard when any of the above need a service...
Oil service
When this light appears in red on your CBS menu, your vehicle is due an oil service or major engine service (depending on the model year and mileage). The service intervals are between 15000 and 20000 miles depending on model.
If you do not cover lots of mileage, an oil service will show on a time based interval (every 2 years).
