Understanding BMW's Condition Based Service (CBS) System

The 2012 BMW 640i Coupe utilizes BMW's Condition Based Service (CBS) system. The maintenance system directs you to required maintenance measures and supports you in maintaining road safety and the operational reliability of the vehicle . Unlike traditional fixed-interval maintenance schedules, CBS uses sensors and special algorithms that take into account the driving conditions of your vehicle to determine maintenance requirements. The system makes it possible to adapt the amount of maintenance you need to your user profile .

Service Data in the Remote Control: Information on the required maintenance is continuously stored in the remote control. Your service center will read out this data and suggest the right array of service procedures for your vehicle. Hand your service specialist the remote control that you used most recently .

Storage Periods: Storage periods during which the vehicle battery was disconnected are not taken into account. If this occurs, have a service center update the time-dependent maintenance procedures, such as checking brake fluid and, if necessary, changing the engine oil and the microfilter/activated-charcoal filter .

OEM Factory Maintenance Schedule

The following maintenance intervals represent the recommended schedule for the 2012 BMW 640i Coupe. Exact intervals are determined by the vehicle's CBS system based on driving conditions.

Ignition Coils

Ignition coils transform battery voltage into the high energy needed for each spark plug . Old ignition coils can impede engine performance by firing out of time with the engine and causing it to work harder than it needs to .

Owner Guidance: Ignition coils are not typically considered a scheduled maintenance item but may require replacement if they fail. A Bosch ignition coil with spark plug connector is a suitable replacement for this vehicle .

Break-In Period

For the first 1,200 miles/2,000 km, do not exceed 4,500 rpm and 100 mph/160 km/h. Avoid full-throttle operation and use of the transmission's kickdown mode for the initial miles. From 1,200 miles/2,000 km, the engine and vehicle speed can gradually be increased .

Brakes require an initial break-in period of approximately 300 miles/500 km to achieve optimized contact and wear patterns between brake pads and discs. Drive moderately during this break-in period .
