Conditional Based Service

CBS is an evolution of BMW’s standard service indicator system previously fitted across the model range. It was first introduced in 2002 when the "new" 7’ series model was launched and is now a standard feature on most new models.

% value of serviceable item means percentage of item usage (e.g. 100% brake pads means completely unused brake pads, 0% totally worn brake pads). In other words, value has to be set to 100% after service maintenance is performed, or adjusted to proper value if no replacement has been made.

BimCOM allows also to set number of times the item was serviced (normally this number is increased by one).

Engine Oil

• The first oil change is due after 20 000 km / 12 427 miles, and then every 30 000 km / 18 641 miles after that.
• The engine oil and oil filter are changed because keeping the oil at the right level and clean is vital to the protection and longevity of the life of movable engine parts. Also, if you do a lot of short journeys, your oil filter will be more susceptible to blockages caused by the condensation of water in the oil.
• The handbrake is checked - unlike the foot brakes, the handbrake is a mechanical function and therefore has to be checked for any necessary adjustment as standard.
• With every 3rd oil change: 1.replace air filter element - this can reduce your fuel consumption by up to 10% as the engine can breathe more easily. 2. replace main fuel filter (only if diesel) - this will ensure a higher purification level of your fuel.

Front Brake Pads

• If the icon is active, the front brake pads are close to their wear limit and need replacing. Your brake discs should also be checked.
• Failure to get your brake pads replaced will result in a reduction in braking performance, and if the callipers are cleaned, any squeaking in the brakes should be diminished.
• Brake discs: surface and thickness - the importance of having a safe level of thickness in brake discs is paramount for driving safety.
• If BimCOM fails to correctly reset the CBS service (or brake pad DTC appears after reset), please check if brake pads sensor is properly connected and functional. This is very common issue.

Rear brake pads

• If the icon is active, the rear brake pads are close to their wear limit and need replacing. Your brake discs should also be checked.
• Failure to get your brake pads matched correctly will result in a brake imbalance front to rear on your vehicle, and if the callipers are cleaned, any squeaking in the brakes should be diminished.
• Brake discs:- Surface and thickness - the importance of having a safe level of thickness in brake discs is paramount for driving safety.
• Handbrake - the handbrake is a mechanical function and therefore has to be checked for any necessary adjustment. As the handbrake is connected to the rear brake shoes over time these shoes wear and therefore these will also require inspection to ensure a serviceable condition.
• If BimCOM fails to correctly reset the CBS service (or brake pad DTC appears after reset), please check if brake pads sensor is properly connected and functional. This is very common issue.

Brake Fluid

• Brake fluid is hydroscopic (absorbs moisture) and so its performance deteriorates over time.
• Replacement brake fluid reduces corrosion of ABS components as well as maintaining braking performance.
• Clean brakes and replace brake pads.
• Check surface and thickness of brake discs.
• Change on two year cycle.
• Brake pads/discs replacement.
• Wearable components within brakes are maintained to ensure high braking performance and safety.

Cabin microfilter

• Microfilter/pollen filter should be replaced with every engine oil service.
• This icon may not displayed in the vehicle.
• BMW filters provide greatly improved air quality in the passenger compartment with triple filtering: mechanical, electrostatic, and activated charcoal.
• BMW recommends microfilters be replaced at intervals of 15 000 miles / 24 140 km. The Vehicle service section will estimate time left until replacement is due.

Particle filter

• Diesel particulate filter catches soot particles from the exhaust and this reduces carbon emissions (CO2) from entering the atmosphere.
• The process for removing the soot is called a "regeneration" this is automatically carried out by your cars engine management system.
• Once your vehicle's diesel particulate filter reaches a temperature of approximately 550 degrees centigrade the process starts.
• Reaching the optimum temperature is the key to ensuring that your car "regenerates".
• Optimum conditions for regeneration are achieved by travelling at 60 km/h (37.2 Mph) with engine revs above 2000 rpm for around 10-15 minutes.

Battery

• The electrical system in late-model BMWs is sophisticated that it tailors charging as closely as possible to both the type and age of the battery.
• When you replace a battery, this computer needs to know if you’ve replaced the battery or updated the vehicle from a conventional Lead Acid battery to an Absorbent Glass Mat (AGM) type.
• There’s a computer that controls the alternator.

QMVH-oil

Spark plugs adaptive

• Replace spark plugs in interval of 60,000 miles / 96 561 km or at every fourth engine oil service.
• Spark plugs are one of the most critical parts of a petrol car's engine.
• Defective spark plugs can result in worsening emissions and increased fuel consumption and can result in misfires.
• Replacing these spark plugs will improve the performance of the engine.

Vehicle check

This thorough inspection covers a wide variety of elements to help ensure your BMW remains safe. Is possible that this symbol may also appear for other vehicle defects.

• Diagnosis test.
• Horn, headlight flasher and hazard warning lights.
• Steering fluid reservoir: fluid level checked.
• Instrument and indication field lighting, check heater blower.
• Windscreen wash/wipe system.
• Coolant level and refill.
• Body: checked for corrosion.
• Brakes or steering.
• Tyres: tread depths, tread pattern and external condition, check inflation pressures.
• Battery: display checked and if necessary replaced.
• Windscreen washer system: check fluid level, top up if necessary.
• Brake lines and connections: check for leaks, damage and correct position.
• Under-body including all visible parts: checked for damage, leaks and corrosion.
• Steering components: checked for clearance, leaks, damage and wear.
