Understanding the BMW Condition Based Service System
The 2012 BMW M3 Coupe is equipped with the Condition Based Service (CBS) system, which represents a significant departure from traditional fixed-interval maintenance. BMW's maintenance guidelines are sensor-driven and center around the CBS system, which is cycled to occur every 10,000 miles, whether it involves a simple oil change and tire rotation or other standard service . Throughout the menu of scheduled services, BMW technicians perform multi-point inspections on fluid levels and other needs of your vehicle.
BMW utilizes electronic oil measurement to monitor the engine load on the current oil fill, based on driving style and distances. This information is monitored on the vehicle's Control Display; if the oil is outside its specified operating range, a Check Control message is displayed . The CBS system is the primary guide for your specific vehicle—the reference intervals provided below should be used for planning, but the CBS system remains the final authority for when service is actually needed.
