• Brake fluid requires replacement after 3 years for the first time, then every 2 years thereafter . The vehicle requires DOT 4 specification brake fluid .
• The microfilter replacement interval is not shown in the CBS system and should be replaced every 2 years based on the vehicle production date .

Understanding the 2012 BMW M6 Convertible (F12 Generation)

The 2012 BMW M6 Convertible is part of the F12 generation, powered by the S63T 4.4L twin-turbo V8 engine. Available in two power outputs—423 kW and 441 kW—this high-performance grand tourer features a retractable hardtop and sophisticated M-tuned chassis.

The Condition Based Service (CBS) System

The 2012 M6 Convertible does not follow a traditional fixed-mileage maintenance schedule. Instead, it employs the Condition Based Service (CBS) system . Sensors and sophisticated 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 driving profile.

Service data is continuously stored and can be read from the vehicle key by your BMW Service Advisor to propose the optimum scope of maintenance . Service requirements can be displayed on the Control Display .

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 .

Never ignore CBS alerts. Prompt attention to service notifications prevents minor issues from developing into costly repairs.

BMW Factory Maintenance Coverage

The 2012 BMW M6 Convertible includes comprehensive factory coverage from its original in-service date :

The BMW Maintenance Program is designed to help reduce the cost of ownership by computing maintenance intervals based upon the specific manner in which each individual vehicle is driven .

BMW offers a Maintenance Program Upgrade for coverage up to 6 years or 100,000 miles. Contact your authorized BMW center for information and availability .

Important: If the vehicle is not maintained according to factory specifications, serious damage could result that is not covered by the BMW New Vehicle Limited Warranty .

Scheduled Maintenance Intervals

The following intervals represent factory-specified guidance for the 2012 BMW M6 Convertible . The CBS system remains the definitive authority for your specific vehicle's needs.

General BMW Maintenance Guidance

BMW's maintenance guidelines are sensor-driven and center around a CBS system that is cycled to occur approximately every 10,000 miles . Throughout scheduled services, BMW technicians perform multi-point inspections on fluid levels and other needs of your vehicle . The remaining times for selected maintenance tasks, as well as any legally prescribed dates, are displayed individually for engine oil, brakes (front and rear separately), brake fluid, vehicle check, and required state inspections .

Engine Oil Service

Factory Guidance

The S63T 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.

• Total Oil Capacity: 9.5 liters
• Recommended Oil Specifications: BMW LL-01 FE approved oils, such as 0W-30 or 5W-30 meeting BMW specifications

Oil Filter: Always replace the oil filter simultaneously with an oil change .

Conservative Owner Guidance

Pelican Parts recommends changing synthetic motor oil every 5,000 miles for optimal engine protection . Motor oil is the single most important element in keeping your engine healthy and helping it to enjoy a long life .

Signs that an oil change may be needed sooner include:

• Check engine/oil change light is on
• Engine knocking sounds
• Oil smell inside the vehicle
• Frequent dusty road driving, heavy loads, or low-speed driving for long distances

BMW utilizes electronic oil measurement to monitor the engine load on the current oil fill based on driving style and distances. It is monitored on the vehicle's Control Display. If outside its specified operating range, a Check Control message is displayed .

Spark Plugs

Factory Guidance

The 2012 M6 Convertible's S63 V8 engine requires spark plug replacement with each second engine oil change .

Important Note: The replacement intervals for the spark plugs are not shown in the CBS display . You must track this based on your oil change count.

Symptoms of Worn Spark Plugs

• Rough idle
• Hesitation during acceleration
• Misfires under load
• Reduced fuel economy
• Check engine lights related to cylinder misfires

Air Filters

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 and prevents contaminants from entering the engine.

Cabin Air Filter (Microfilter)

The cabin air filter (microfilter) should be replaced at every engine oil change or every 2 years based on the vehicle production date .

Important Note: The replacement intervals for the microfilter are not shown in the CBS display . This is a time-based service that must be tracked separately.

Brake Fluid

Factory Guidance

Brake fluid replacement is a time-based, safety-critical service. BMW recommends replacing brake fluid after 3 years for the first time, then every 2 years thereafter .

Brake Fluid Specification: DOT 4 specification brake fluid . Low-viscosity BMW/MINI formula is ideal for extreme braking conditions .

Significance: Brake fluid is hygroscopic—it absorbs moisture from the atmosphere over time. Pelican Parts recommends changing brake fluid every time you service your brakes .

Note: Brake fluid replacement is displayed in the CBS system .

Rear Axle Differential Oil

The rear axle differential oil should be replaced with each third engine oil change . 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 2012 M6 Convertible is equipped with a 7-speed M DCT (Double-Clutch Transmission).

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.

Long-Term Ownership Considerations

S63 Engine-Specific Considerations

The S63 4.4L twin-turbo V8 is a high-performance engine that requires diligent maintenance. Key considerations include:

Cooling System: The S63 generates significant heat. Multiple service bulletins address coolant leaks from the coolant pump and turbocharger coolant lines. Regular inspection of the cooling system is recommended.

High-Pressure Fuel Injectors: BMW has issued service bulletins addressing high-pressure fuel injector procedures for N63 and S63 engines. Symptoms include rough running, misfires, and cold start issues.

DCT Transmission: Correct diagnosis of DCT oil leaks is important to avoid unnecessary part replacements.

High-Mileage Maintenance Planning

For owners accumulating significant mileage, additional services become relevant:

60,000-100,000 Miles:

• Transmission fluid service (recommended by independent specialists for performance-driven vehicles)
• Engine air filter replacement (if not already done at second oil change intervals)
• Cooling system inspection and possible flush

100,000+ Miles:

• Oxygen sensor replacement
• Full transmission service
• Comprehensive vehicle inspection
