Understanding BMW's Condition Based Service (CBS) System

The 2017 BMW 640i xDrive 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 user profile, considering factors such as trip length, engine temperature, and driving style.

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. Storage periods during which the vehicle battery was disconnected are not taken into account; 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 .

OEM Factory Maintenance Schedule

The following maintenance intervals represent the key factory-recommended milestones for the 2017 BMW 640i xDrive 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 640i xDrive Coupe uses the N55 engine. 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 meeting BMW specifications
• The specific viscosity should be selected based on climate and driving conditions as specified in your owner's manual

Conservative Owner Guidance: Pelican Parts recommends changing your synthetic motor oil every 5,000 miles for optimal engine protection . Always replace your filter when changing your oil. Different engines and climates require specific oil viscosities—be sure to refer to your owner's manual for the type and viscosity of oil required for your car .

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
• Frequent hauling of heavy loads, driving in dusty areas, off-roading, or low-speed long-distance trips

Spark Plug Service

The 2017 BMW 640i xDrive Coupe uses Bosch spark plugs as original equipment . The N55 engine requires 6 spark plugs .

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 . 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 .

Spark Plug Inspection: Check for abnormal pitting or charred plug ends when replacing. Any strange variations among plugs are a sure indicator that something is wrong with a particular cylinder .

Brake System Service

BMW generally 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 the tires
• An illuminated brake dashboard warning light

Brake Fluid Service

The 2017 BMW 640i xDrive Coupe uses DOT4 specification brake fluid . Brake fluid is a hydraulic fluid specially formulated to withstand the extreme pressures and temperatures of your braking system . Brake fluid should be changed every time you service your brakes .

OEM Guidance: Brake fluid service is indicated by the CBS system. Over time, the brake fluid absorbs air, moisture, sludge, and other contaminants . Air in the brake fluid causes braking to feel spongy and significantly reduces braking efficiency . A brake system flush includes removing the existing fluid and moisture out of the system and replacing it with new, clean fluid .

Conservative Owner Guidance: It is a good practice to change brake fluid every 24,000 miles or 36 months . Always use a fluid recommended by the vehicle manufacturer .

Brake Fluid Specifications:

• DOT4 specification
• Dry Boiling Point: 280°C (536°F)
• Wet Boiling Point: 198°C (388°F)

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.

Differential Fluid Service

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.

xDrive Transfer Case Service

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.

Service Interval Warning System

The 2017 BMW 640i xDrive Coupe includes a service interval warning in the instrument cluster, which notifies the driver when maintenance is due . This is part of the CBS system that helps owners stay aware of all aspects of their maintenance schedules.

BMW Maintenance Program Coverage

The 2017 BMW 640i xDrive 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 proper maintenance, a 2017 BMW 640i xDrive Coupe has a good chance of hitting 200,000 miles or more . Staying on track with routine service appointments can help your 640i xDrive Coupe perform better, keep you safer 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 .
