Understanding the 2007 BMW M6

The 2007 BMW M6, offered as a coupe (E63) and convertible (E64), is powered by the legendary S85B50 5.0L naturally aspirated V10 engine. This engine is a milestone in BMW's history, derived from Formula 1 technology and producing 500 horsepower at 7,750 rpm . Its high-revving, high-compression design demands meticulous maintenance.

The S85 V10 Engine: Critical Considerations

The S85 V10 is a masterpiece of engineering but has several well-documented maintenance requirements that owners must respect:

• Rod Bearings: Premature rod bearing wear is the most well-known issue with the S85 engine. The factory clearances were insufficient for the high-revving design, requiring replacements every 60,000–80,000 miles .
• VANOS System: The variable valve timing system (VANOS) is prone to solenoid failure, which can result in rough idle, loss of power, or check engine lights .
• Throttle Actuators: The electronic throttle actuators can fail due to worn gears, leading to limp mode. Replacements are common at higher mileages .
• Cooling System: Cooling system components, including the water pump and thermostat, often fail prematurely, risking engine overheating .
• SMG Hydraulic Pump: Owners noticed occasional hesitation during shifts occurred when the motor struggled to build hydraulic pressure quickly enough .

BMW Factory Maintenance Programs

BMW Ultimate Care

The 2007 BMW M6 included BMW's Ultimate Service program, which provided complimentary scheduled maintenance for 4 years or 50,000 miles from the vehicle's original in-service date . This coverage included engine oil and filter changes, brake fluid flushes, spark plug replacements, and vehicle checks.

Condition Based Service (CBS) System

BMW's maintenance guidelines are sensor-driven and center around a Condition Based Service (CBS) system that is cycled to occur approximately every 10,000 miles . BMW utilizes electronic oil measurement to monitor the engine load on the current oil fill based on driving style and distances, displayed on the vehicle's Control Display.

Scheduled Maintenance Intervals

The following intervals represent factory-specified maintenance for the 2007 BMW M6 . A conservative, preventive approach is strongly recommended for the S85 engine .

Engine Oil Service

Factory Guidance

The S85 V10 engine requires BMW-approved 10W-60 oil, which is critical for protecting the engine's bearings and valvetrain at extreme temperatures . The original factory-fill oil was Castrol TWS Motorsport 10W-60, now available as BMW M TwinPower Turbo 10W-60.

Engine Oil Capacity: The S85 uses a quasi-dry sump oil system. The approximate capacity when performing an oil service is 8.8 liters, following a specific procedure, not the 9.3 liters stated in the owner's manual . Overfilling can cause issues.

Special Oil Service Procedure:

1. Run the engine at idle at operating temperature (oil temperature >70°C) for one minute to pump oil from the front oil pan area to the rear sump .
2. Drain the engine oil and replace the filter element and sealing rings.
3. Refill with 8 liters of Castrol TWS Motorsport SAE 10W-60 Synthetic Oil .
4. Run the engine until operating temperature is reached and check the oil level using the BC function.
5. Correct by adding the calculated top-off quantity as needed. Never overfill above MAX .

Important CBS Reset Note: At the 1,200-mile running-in inspection, the CBS reset must only be performed using the GT1/DISplus. This ensures the DME changes the oil level calculation algorithm for the break-in oil to that needed for the 10W-60 synthetic oil .

Conservative Owner Guidance

Motor oil is the single most important element in keeping the S85 engine healthy. While the CBS system may suggest longer intervals, independent specialists recommend changing the oil every 5,000 miles to minimize wear on the sensitive bearings .

Signs that an oil change may be needed sooner include:

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

Spark Plugs

Factory Guidance

The 2007 BMW M6's S85 V10 engine requires spark plug replacement at 37,000-mile intervals . The engine requires 10 spark plugs, with Genuine BMW part number 12-12-0-032-273 .

Factory Replacement Schedule: 37,000 miles, 74,000 miles, 111,000 miles, 148,000 miles .

Symptoms of Worn Spark Plugs

• "Engine Fault" codes that may seem intermittent
• Reduced performance
• Increased emissions
• Rough idle

Brake Service

Brake Inspection

BMW generally recommends that front and rear brakes be removed and serviced at least once every 12 months or 12,000 miles . This includes checking the parking brake.

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

Signs of brake problems include:

• Unusual sounds from the brakes
• Vibration or pulsation in the pedal or steering wheel
• Burning smell around the tires
• Dashboard brake light illuminated
• A sensation that braking performance has changed

Rod Bearings

Enthusiast Guidance

The S85 V10 engine has a well-documented vulnerability regarding its rod bearings. BMW's original bearings and oil clearances were insufficient for the high-revving design, requiring replacements every 60,000–80,000 miles .

Independent specialists and aftermarket suppliers offer replacement bearings designed with extra clearance to address this flaw. Many enthusiasts consider rod bearing replacement a mandatory preventive service on higher-mileage S85 engines.

Symptoms of failing rod bearings include:

• Metallic knocking sounds from the engine, especially at cold start
• Metal particles in the oil filter
• Low oil pressure warnings

Transmission Care

SMG Transmission

Most S85-equipped cars were paired with the SMG III single-clutch automated manual transmission, which is known for jerky shifts and frequent hydraulic pump failures . A general rule of thumb is to have your transmission fluid checked and changed about every 30,000 to 60,000 miles . Service intervals can vary depending on driving habits.

For the SMG transmission, maintaining the hydraulic system is critical, and some owners consider converting to a manual gearbox for improved reliability .
