2017 BMW 650i xDrive Gran Coupe Complete Maintenance Schedule & Service Guide

Key Takeaways

• The 2017 BMW 650i xDrive Gran Coupe is powered by the N63 4.4L twin-turbo V8 engine and features xDrive all-wheel drive. BMW issued a service bulletin reducing the CBS engine oil service interval to 1 year/10,000 miles for this N63 engine-equipped vehicle .
• Major factory-scheduled maintenance milestones include spark plug replacement at 60,000 miles, oxygen sensor replacement at 120,000 miles (repeat at 150,000), and another spark plug service at 120,000 miles .
• Brake system service is recommended at least once every 12,000 miles or 12 months; brake pads typically last between 30,000 and 40,000 miles depending on driving habits .
• The vehicle uses BMW-approved synthetic oil meeting BMW Longlife-01 (LL-01) specifications. For vehicles over 75,000 miles, some references suggest switching to high-mileage oil .

Understanding BMW's Condition Based Service (CBS) System

The 2017 BMW 650i xDrive Gran Coupe utilizes BMW's Condition Based Service (CBS) system. Unlike traditional fixed-interval maintenance, CBS uses sensors and algorithms that take into account the driving conditions of your vehicle to determine when maintenance is required. The system adapts the amount of maintenance to your specific driving profile, considering factors such as trip length, engine temperature, and driving style.

BMW's maintenance guidelines are sensor-driven and center around the CBS system, which is cycled to occur approximately every 10,000 miles . Synthetic oil and oil filter changes typically occur every 10,000 miles or 12 months, whichever occurs first. Coolants are also checked at the 10,000-mile mark . Service information is stored in the vehicle's remote key fob, which your BMW Service Advisor can read to propose the precise maintenance procedures needed for your vehicle.

Important Note for N63 Engine: BMW issued Service Bulletin B012418 for affected vehicles, which reduces the CBS engine oil service interval to 1 year/10,000 miles to make these vehicles consistent with all other N63x engine-equipped vehicles . BMW also issued Service Bulletin B110113 addressing N63 engine oil consumption concerns, with specific procedures for top-ups and refill capacity .

Factory Recommended Maintenance Schedule

The following maintenance intervals represent key factory-recommended milestones for the 2017 BMW 650i xDrive Gran Coupe. Exact intervals are determined by the vehicle's CBS system based on driving conditions .

Engine Oil and Filter Change

Motor oil is the single most important element in keeping your engine healthy and helping it to enjoy a long life. The 2017 650i xDrive Gran Coupe uses the N63 4.4L twin-turbo V8 engine, which requires high-quality synthetic oil.

Oil Change Guidance:

BMW has specified a reduced oil service interval of 1 year/10,000 miles for the N63 engine through a Service Action . BMW recommends having your motor oil changed at regular intervals. Your 650i xDrive Gran Coupe may need an oil change sooner if:

• The check engine/oil change light is on
• You hear knocking sounds coming from the engine
• You sense an oil smell in the cabin
• You see an excess amount of vehicle exhaust

More frequent oil changes may be needed if you regularly haul heavy loads, drive in dusty conditions, or drive at low speeds for long distances. In general, being extra-diligent about oil changes won't damage your BMW—each oil change is another chance to check and resolve other car issues, such as worn brake pads or tire treads.

Conservative Owner Guidance: Independent specialists recommend changing your synthetic motor oil every 5,000 miles for optimal engine protection. A 5,000-mile oil service interval is preferred for aggressive or city driving.

High-Mileage Consideration: If your BMW 650i xDrive Gran Coupe has ticked past 75,000 miles, some references suggest considering switching to high-mileage oil at your next oil change .

Oil Specifications:

• BMW-approved synthetic oil meeting BMW Longlife-01 (LL-01) specifications
• BMW has recommendations as to whether conventional or synthetic oil is best for your vehicle
• Always replace the oil filter when changing your oil

Spark Plug Service

Spark plugs are small but vital components—the spark of electricity that the plug emits across a small gap creates the ignition for the combustion needed to start your car. Without that spark, your car won't start .

Service Interval: Spark plugs are recommended for replacement at 60,000 miles, with a repeat service at 120,000 miles . For N63R V8 engines, some references recommend replacing spark plugs every 30,000 to 40,000 miles, especially if the vehicle has been tuned for increased performance .

Spark Plug Guidance: Replacing spark plugs on time or about every 30,000 miles is recommended to sustain peak engine performance . The N63 V8 engine requires 8 spark plugs. Ignition coils can last 80,000-100,000 miles, but can also fail much sooner. Proactive replacement is recommended by the 90,000-mile mark .

Symptoms of Spark Plug Issues:

• Shaking while the engine is idling
• Poor fuel economy
• Engine knocking
• Illuminated check engine light

Oxygen Sensor Service

Service Interval: Oxygen sensors are scheduled for replacement at 120,000 miles, with a repeat service at 150,000 miles . Replacement helps maximize fuel economy and minimize exhaust pollution.

Brake System Service

BMW suggests that at a minimum, front and rear brakes are removed and serviced at least once every 12,000 miles or 12 months, including checking the parking brake .

Brake Pad Life: The majority of brake pads last between 30,000 and 40,000 miles. If you drive mostly on the highway and tend to brake smoothly, your brake pads may last longer. If you often haul heavy loads or ride your brakes, your brake pads may wear out sooner .

Signs of Brake Issues:

• Unusual noises (squealing or grinding)
• Vibration or pulsation in the steering wheel or pedal
• A burning smell near the tires
• Illuminated brake dashboard warning light

Brake Fluid Service

Brake fluid is a hydraulic fluid specially formulated to withstand the extreme pressures and temperatures of your braking system. Brake fluid should be checked and changed as part of regular brake service.

Fluid Guidance: Brake fluid is hygroscopic—it absorbs moisture from the atmosphere over time, which lowers its boiling point and compromises braking performance. A conservative approach is to flush and replace brake fluid every 2 years regardless of mileage.

Wheel Alignment

It is generally recommended to have wheel alignment checked approximately every 6,000 miles or 6 months .

Signs Alignment May Need Attention:

• A feeling that your car pulls to one side
• Rapid or uneven tire wear
• A steering wheel that feels off center or crooked while driving straight
• Tires that squeal frequently

Unlike with other potential issues, you won't see any dashboard warning lights if your wheel alignment needs attention .

Transmission Service

The 2017 650i xDrive Gran Coupe is equipped with an 8-speed automatic transmission. BMW's original maintenance schedule classifies the transmission fluid as "lifetime fill" under normal conditions.

Conservative Owner Guidance: A conservative maintenance approach is to service the transmission as preventative maintenance at regular intervals to avoid potential failure. If left unserviced, the automatic transmission fluid will break down over time, potentially leading to poor shifting, slipping, and ultimately transmission failure.

Battery Care

Batteries generally need to be replaced every three to five years . Yours may need to be replaced sooner depending on your driving habits and climate. Short trips and extreme temperatures can shorten the overall life expectancy of your BMW 650i xDrive Gran Coupe battery .

Engine Tune-Up Signs

Pay attention to warning signs that your engine may need attention:

• Stalling or shaky idling when stopped
• Diminished fuel economy
• Knocking noises in the engine
• A lit check engine light on your dashboard

Long-Term Ownership Outlook

With proactive maintenance, a 2017 BMW 650i xDrive Gran Coupe could be on the road well past the 200,000 mile mark . Staying on track with routine service appointments can help your 650i xDrive Gran Coupe perform better, increase your vehicle safety, and help you avoid expensive repairs.

Regular maintenance is an investment that maintains the value and dependability of your car, extends its service life, and increases its resale value. Good maintenance should never be viewed as an expense—it is an investment in the longevity and reliability of your BMW.
