Understanding BMW's Condition Based Service (CBS) System

The 2017 BMW 640i xDrive Gran Coupe utilizes BMW's Condition Based Service (CBS) system. The maintenance system directs you to required maintenance measures and supports you in maintaining road safety and the operational reliability of the vehicle . Unlike traditional fixed-interval maintenance schedules, CBS uses sensors and special algorithms that take into account the driving conditions of your vehicle to determine maintenance requirements . The system makes it possible to adapt the amount of maintenance you need to your user profile.

Service information on required maintenance is continuously stored in the remote control. Your service center will read out this data and suggest the right array of service procedures for your vehicle . The recommended maintenance schedule is put together by BMW, your vehicle manufacturer .

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.

Engine Specifications & Capacities

The 2017 BMW 640i xDrive Gran Coupe is equipped with the N55 3.0L turbocharged inline-six engine (engine codes N55B30/N55B30O0) .

OEM Factory Maintenance Schedule

The following maintenance intervals represent the key factory-recommended milestones for the 2017 BMW 640i xDrive Gran Coupe. Exact intervals are determined by the vehicle's CBS system based on driving conditions .

60,000 Mile Service

At 60,000 miles, the key scheduled maintenance item is replacing the spark plugs .

• Replace Spark Plugs

120,000 Mile Service

At 120,000 miles, multiple key services are recommended :

• Replace Spark Plugs
• Replace Oxygen (O2) Sensor

150,000 Mile Service

At 150,000 miles, the oxygen sensors require replacement again :

• Replace Oxygen (O2) Sensor

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 640i xDrive Gran Coupe uses the N55 engine with an oil capacity of 6.5 liters . BMW's CBS system will indicate when an oil service is due, with typical intervals around 10,000 miles depending on driving conditions .

Oil Specifications:

• BMW-approved synthetic oil
• The specific viscosity should be selected based on climate and driving conditions as specified in your owner's manual

Conservative Owner Guidance: More frequent oil changes are advisable if you regularly haul heavy loads, drive in dusty areas, off-road, or drive at low speeds for long distances . Generally, getting more frequent oil changes won't hurt your BMW. In fact, more frequent oil changes give technicians more opportunities to catch and alert you to any issues, like worn brake pads or a weak battery . A conservative approach is to change synthetic motor oil every 5,000 miles for optimal engine protection .

Signs Your Vehicle May Need an Oil Change Sooner :

• Check engine/oil change light is illuminated
• Knocking sounds from the engine
• Oil smell inside the vehicle
• Excess amount of vehicle exhaust

Spark Plug Service

Spark plugs are small but vital—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 . The 2017 BMW 640i xDrive Gran Coupe uses Bosch spark plugs as original equipment.

OEM Interval: Spark plugs are scheduled for replacement at 60,000 miles, with a repeat service at 120,000 miles .

Conservative Owner Guidance: Some service providers recommend replacing spark plugs on time or about every 30,000 miles . Replace spark plugs on time based on BMW's recommendations.

Oxygen Sensor Service

OEM Interval: Oxygen sensors are scheduled for replacement at 120,000 miles, with a repeat service at 150,000 miles . Oxygen sensors deteriorate on a mileage basis, and replacement helps maximize fuel economy and minimize exhaust pollution.

Brake System Service

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

Signs of Brake Issues :

• Unusual noises (squealing or grinding)
• Vibration or pulsation in the steering wheel or pedal
• A burning smell near your tires
• An illuminated brake dashboard warning light
• A sensation that things aren't like they used to be

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 changed when indicated by the CBS system or as a regular preventative service.

Conservative Owner 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 .

Differential Fluid Service (xDrive)

Differential oil lubricates and assists in the heat dissipation of the differential . It should be checked for level and changed as per the owner's manual recommendation .

Fluid Specification: Fully synthetic gear oil is recommended for vehicles with standard differentials . Genuine BMW 75W-90 full synthetic multigrade final drive lubricant is specially designed for use in all BMW final drives with conventional (non-limited slip) differentials, providing superior protection at high and low operating temperatures .

xDrive-Specific Note: The xDrive all-wheel-drive system includes both front and rear differentials. Ensure both are serviced when differential fluid is due.

xDrive Transfer Case

The xDrive transfer case requires periodic fluid service using BMW-approved transfer case fluid. Regular fluid service is critical for proper xDrive operation and system longevity.

Battery Care

Batteries generally need to be replaced every three to five years . Extremely hot or cold temperatures can take a toll on your BMW battery, and so can frequent short drives . If you keep driving on a battery that can't hold a charge, you run the risk of being stranded when your battery finally gives out . The battery registration process should be performed when replacing the battery to ensure proper charging characteristics.

Engine Tune-Up Signs

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

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

BMW Maintenance Program Coverage

The 2017 BMW 640i xDrive Gran Coupe was covered by BMW's standard maintenance program from the original in-service date. For vehicles beyond this coverage, owners should plan for out-of-pocket maintenance.

Long-Term Ownership Outlook

With proactive maintenance, a 2017 BMW 640i 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 640i xDrive Gran Coupe perform better, decrease your risk of dangerous malfunctions on the road, 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 . Scheduled maintenance services can vary depending on driving conditions, climate, and other factors; however, recommended maintenance usually includes services like oil changes, tire rotations, brake pad replacement, filter changes, and fluid checks and exchanges .
