Condition Based Servicing (CBS)
Newer BMW models feature a technology at the forefront of service innovation called Condition Based Service, which ensures your BMW only receives attention when it needs it, saving time and money. CBS sensors monitor the condition of certain service parts and fluids. A microchip in your remote control key stores the data, which our BMW Approved Technicians download via a KeyReader. We use Genuine BMW Parts to restore your BMW to optimum condition.
Please see below for a how to guide for you model.
 | Engine oil |
 | Front brakes |
| • Engine oil and oil filter changed
• Check handbrake • Air filter and fuel filter replaced periodically (change cycle depends on model) • An oil change can increase the longevity of the engine parts. Replacement of filters can reduce fuel consumption | • Brakes are maintained to ensure high
performance and constant safety • Clean brakes • Replace brake pads and wear sensors if necessary • Replace brake discs if worn to recommended change point | ||
 | Vehicle check |
 | Rear brakes |
| • Check condition of vehicle
systems including: • Exterior panelling and underbody for corrosion and damage • Tyres, steering and shock absorbers • Electrical systems including battery, headlights and indication field lighting • Safety including brakes and seat belts • Check coolant and fluid levels | • Brakes are maintained to ensure high
performance and constant safety • Clean brakes • Replace brake pads and wear sensors if necessary • Replace brake discs if worn to recommended change point | ||
 | Micro filters |
 | Spark plugs |
| • Replace micro filter/pollen filter in heating
or air conditioning system to prevent pollen or dust entering through the vents • Micro filters trap 80% of pollen and traffic fumes maintaining a pleasant passenger environment. They also ensure fast demisting in winter | • Replace worn or defective spark plugs
to ensure optimum performance, fuel economy and low emissions • Replacement spark plugs will improve engine performance and avoid any chance of engine misfire | ||
 | Brake fluid |
 | MOT |
| • Replace brake fluid every two years:
brake fluid is hydroscopic (absorbs moisture) and so its performance deteriorates over time • Replacement brake fluid reduces corrosion of ABS components and steel pistons as well as maintaining braking performance | • Statutory inspection for vehicles three
years and older • Annual check comprising of over 150 safety-related items and emission system test • Items checked include headlights, steering, brakes, suspension, instrument cluster, seats/seatbelts, windscreen/wipers, VIN, doors and wheels/tyres | ||
 | Diesel filter | Standard scope | |
| • Replace diesel fuel filter ensuring
particle-free fuel providing optimum fuel flow and performance • Replacement diesel filter important in engine efficiency |
• Carried out at every visit including
diagnostic interrogation, check indicator and warning lights on instrument cluster and reset CBS display • Check and verify any control messages |
