• Brake fluid (DOT 4 Class 6) requires replacement after 3 years, then every 2 years thereafter, with a capacity of approximately 1.06 US quarts .
• Engine air filter replacement is scheduled for every second engine oil change, and the cabin microfilter should be replaced at every oil change .

Understanding BMW's Condition Based Service (CBS) System

The 2014 BMW M6 Coupe (F13 generation) does not follow a traditional fixed-mileage maintenance schedule. Instead, it employs BMW's Condition Based Service (CBS) system . Sensors and special algorithms take into account the driving conditions of your vehicle—including engine temperature, driving style, trip length, and component wear—to determine maintenance requirements . The system makes it possible to adapt the amount of maintenance to your individual user profile .

Service requirements can be displayed on the Control Display . Service data is continuously stored in the remote control, and your service center will read out this data to suggest the right array of service procedures for your vehicle . For this reason, hand your service specialist the remote control with which the vehicle was driven most recently .

Important Note on Storage Periods: Storage periods during which the vehicle battery was disconnected are not taken into account by the CBS system. If this occurs, have a service center update the time-dependent maintenance procedures, such as checking brake fluid and, if necessary, changing the engine oil and the microfilter/activated-charcoal filter .

BMW Factory Maintenance Coverage

The 2014 BMW M6 Coupe includes comprehensive factory coverage from its original in-service date. The Service and Warranty Information Booklet provides additional information on service requirements. BMW recommends that regular maintenance procedures be recorded in the vehicle's Service and Warranty Information Booklet as proof of regular maintenance .

Scheduled Maintenance Intervals

The following intervals represent factory-specified guidance for the 2014 BMW M6 Coupe. The CBS system remains the definitive authority for your specific vehicle's needs.

Fixed Mileage Milestones

The following fixed mileage milestones are documented for the 2014 BMW M6 Coupe :

Engine Oil Service

Factory Guidance

The S63 4.4L twin-turbo V8 engine requires BMW Longlife-approved fully synthetic oil. The CBS system determines the exact oil change interval according to the service display . Motor oil is the single most important element in keeping your engine healthy .

Oil Filter: Always replace the oil filter simultaneously with an oil change. Different engines and climates require specific oil viscosities—be sure to refer to your owner's manual for the type and viscosity of oil required for your car .

Conservative Owner Guidance

Pelican Parts recommends changing synthetic motor oil every 5,000 miles for optimal engine protection . Signs that an oil change may be needed sooner include a check engine light, engine knocking sounds, oil smell inside the vehicle, excess vehicle exhaust, or frequent dusty road driving, heavy loads, or low-speed driving for long distances . Generally, getting more frequent oil changes won't hurt your BMW M6 Coupe. In fact, more frequent oil changes give technicians more opportunities to catch and alert you to any issues .

Spark Plugs

Factory Guidance

The 2014 M6 Coupe's S63 V8 engine requires spark plug replacement at 60,000 miles . The engine uses eight spark plugs. Weak coils or worn plugs cause misfires, rough idle, hard starts, and poor mileage . New coils and plugs restore crisp throttle response and cleaner emissions .

Symptoms of Worn Spark Plugs:

• Rough idle
• Hesitation during acceleration
• Misfires under load
• Reduced fuel economy
• Hard starts

Cost Estimate

A spark plug replacement for the 2014 BMW M6 Coupe is estimated at approximately $465 for parts and labor .

Brake Fluid

Factory Guidance

Brake fluid replacement is a time-based, safety-critical service. BMW recommends brake fluid replacement after 3 years for the first time, then every 2 years thereafter . Air in the brake fluid causes braking to feel spongy and significantly reduces braking efficiency .

Brake Fluid Specification: DOT 4 Class 6 . Do not use silicone-based brake fluids if your vehicle requires regular brake fluid .

Capacity: Approximately 1.06 US quarts .

Brake Inspection: BMW suggests that rear and front brakes are removed and serviced at least once every 12 months or 12,000 miles .

Signs of brake problems include :

• Weird noises from the brakes
• Vibration or pulsation in the steering wheel or pedal
• Burning smell around the tires
• Illuminated brake dashboard light
• A sensation that something's not right

Brake Pad Lifespan: Brake pads often last 30,000 to 40,000 miles, depending on driving style and terrain .

Cost Estimate

A brake system flush for the 2014 BMW M6 Coupe is estimated at approximately $199 for parts and labor .

Engine Air Filter

The engine air filter should be replaced with each second engine oil change . A clean engine air filter ensures optimal airflow for combustion, enhancing engine efficiency and preventing contaminants from entering the engine.

Cabin Air Filter (Microfilter)

The cabin air filter (microfilter) should be replaced at every engine oil change . This filter removes pollen, dirt, and harmful airborne pollutants from the cabin air and maintains HVAC system performance. If the vehicle has been in storage with the battery disconnected, have a service center update the time-dependent maintenance procedures for the microfilter .

Differential Fluid

The 1,200-mile break-in service includes differential fluid replacement . This service is particularly important for the M6's Active M Differential, which uses electronically controlled multi-plate clutches and requires specific oil grades.

Transmission Fluid

The 2014 M6 Coupe is equipped with a 7-speed M DCT (Double-Clutch Transmission). A service bulletin (280114) addresses proper diagnosis of DCT oil leaks to avoid unnecessary part replacements .

Service Consideration: While the BMW factory schedule does not specify a fixed interval for transmission fluid replacement under normal driving conditions, many independent specialists recommend transmission fluid changes at major service intervals for performance-driven vehicles. Check your owner's manual for the exact transmission fluid specification for your vehicle.

Oxygen Sensors

The factory schedule for the 2014 BMW M6 Coupe indicates oxygen (O2) sensor replacement at 120,000 miles and again at 150,000 miles . A failing oxygen sensor can harm performance and fuel mileage and affect drivability .
