The BMW M5 service concept starts in the vehicle itself. Condition Based Service (CBS) continuously checks the status of the M5's individual parts, fluid levels and mileage data and makes this information available to drivers. And thanks to the unique connectivity of the CBS system, your BMW service partner has instant access to essential information about your car's service needs. The result: complete transparency, reduced costs and a well maintained BMW M5 - intelligent service at its most advanced.
