Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
5.0 Condition Based Service
Models: E90, E60, E61, E63, E64 E65, E66
Condition Based Service measures, monitors, and determines the required maintenance of several service items independent from each other. This technology prompts the customer to bring the vehicle for service whenever one of the CBS items requires maintenance or replacement. CBS strikes a compromise between too frequent maintenance and too rigid service intervals that call for the replacement of service items which may still have substantial remaining useful life. CBS also details the recommended, due, and overdue required maintenance during and after the BMW Vehicle Maintenance Program Agreement. Thus, CBS allows BMW customers to experience a technology that makes service more convenient, transparent and structured.
For E90 please refer to S.I. Bulletin B00 01 05 New Vehicle Preparation and Maintenance Requirements.
For E60, E61, E63, E64 E65, E66 please refer to S.I. Bulletin B00 07 02 Condition Based Service (CBS).
