Understanding BMW's Condition Based Service (CBS) System

The 2016 BMW 640i xDrive Gran Coupe utilizes BMW's Condition Based Service (CBS) system. Unlike traditional fixed-interval maintenance schedules, 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 .

Service information on required maintenance is continuously stored in the vehicle's remote key fob. Your service center will read out this data and suggest the appropriate service procedures for your vehicle . The recommended maintenance schedule is put together by BMW, the 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 2016 BMW 640i xDrive Gran Coupe is equipped with the N55 3.0L turbocharged inline-six engine .

OEM Factory Maintenance Schedule

The following maintenance intervals represent the key factory-recommended milestones for the 2016 BMW 640i 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 2016 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

Owner Guidance: More frequent oil changes are advisable if you regularly haul heavy loads, drive in dusty areas, go off-road, 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 actually another chance to check and resolve other car issues, such as worn brake pads or tire treads .

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 2016 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 .

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.

Ignition Coils: Coils transform battery voltage into the high energy needed for each spark plug. Weak coils or worn plugs cause misfires, rough idle, hard starts, and poor mileage . Although ignition coils are sold individually, they should be replaced as a full set when individual coils fail.

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 Fluid Service

Brake fluid is a hydraulic fluid specially formulated to withstand the extreme pressures and temperatures of your braking system . The 2016 BMW 640i xDrive Gran Coupe uses DOT4 specification brake fluid .

Brake Fluid Specifications (DOT4):

• Dry Boiling Point: 280°C (536°F)
• Wet Boiling Point: 198°C (388°F)

Guidance: Brake fluid deteriorates over time and eventually needs to be replaced with a brake system flush . If you notice that your brake fluid appears black or brown, it is well past time for a service . A brake system flush removes existing fluid and moisture out of the system and replaces it with new, clean, fluid. A brake fluid flush ensures proper brake system performance and increases the lifespan of your brake system components .

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 soft or spongy brake pedal

Differential Fluid Service (xDrive)

The xDrive all-wheel-drive system includes both front and rear differentials. Differential oil should be checked for level and changed as per the owner's manual recommendation .

Guidance: Differential service frequency varies from car to car. It is generally recommended to get your differential inspected and the differential fluid changed as a part of your regular vehicle maintenance routine, since your vehicle cannot function without a differential .

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.

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

Long-Term Ownership Outlook

With proactive maintenance, a 2016 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 .
