Understanding BMW's Condition Based Service (CBS) System

The 2014 BMW 428i xDrive Coupe is equipped with BMW's Condition Based Service (CBS) system . Unlike traditional fixed-interval maintenance schedules, this intelligent system uses sensors and special algorithms that take the driving conditions of your vehicle into account. Based on this data, CBS determines the exact maintenance requirements needed for your specific vehicle, allowing service intervals to adapt to your individual driving profile .

Service Data in the Remote Control

Information on required maintenance is continuously stored in your vehicle's remote control key . Your service center will read this data and suggest the right array of service procedures for your vehicle. When taking your car in for service, it is recommended to hand your service specialist the remote control that was most recently used to drive the vehicle .

Storage Periods

The CBS system does not account for periods when the vehicle battery was disconnected. If this occurs, have your service center update time-dependent maintenance procedures such as checking the brake fluid and, if necessary, changing the engine oil and microfilter/activated-charcoal filter .

Service Interval Warning

This vehicle is equipped with a standard service interval warning system that will alert you when maintenance is due .
