Understanding BMW's Condition Based Service (CBS) System

The 2017 BMW 640i Gran Coupe utilizes BMW's Condition Based Service (CBS) system. Unlike traditional fixed-interval maintenance schedules, CBS uses sensors and special algorithms that take into account the driving conditions of your vehicle to determine when maintenance is required. The system adapts the amount of maintenance you need to your specific user profile, considering factors such as trip length, engine temperature, and driving style.

Service information is continuously stored in the vehicle's remote key fob, allowing your service center to read this data and suggest the appropriate service procedures for your vehicle. The CBS system monitors engine oil, brake pads (front and rear separately), brake fluid, and other components.

Storage periods during which the vehicle battery was disconnected are not automatically accounted for by the CBS system. If this occurs, have a service center update time-dependent maintenance procedures such as brake fluid checks and engine oil changes.

OEM Factory Maintenance Schedule

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

Engine Oil and Filter Change

The 2017 640i Gran Coupe uses the N55 3.0L turbocharged inline-six engine . BMW's CBS system will indicate when an oil service is due, with intervals determined by driving conditions .

Oil Specifications:

• BMW-approved synthetic oil (0W-20 recommended for all temperatures )
• BMW recommends either synthetic or conventional as the ideal engine oil for your 2017 640i Gran Coupe
• The oil filter should always be replaced at every oil change

Conservative Owner Guidance:

Motor oil is the single most important element in keeping your engine healthy. More frequent oil changes are advisable if you regularly haul heavy loads, drive in dusty areas, go off-roading, or drive at low speeds for long distances . Being extra-diligent about oil changes won't damage your BMW—each oil change is an opportunity to check and resolve other car issues, such as worn brake pads or tire treads .

Signs that your 640i Gran Coupe may need an oil change sooner than scheduled include:

• Check engine light illuminated
• Knocking noises from the engine
• Oil smell inside the vehicle
• Excess vehicle exhaust

Brake System Service

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

Brake Pad Life:

The majority of brake pads last between 30,000 and 40,000 miles. Factors like frequent highway driving and smooth braking can help your brake pads last longer, while heavy loads and aggressive braking may cause them to wear out sooner .

Brake Fluid Maintenance:

Brake fluid deteriorates over time and eventually needs to be replaced with a brake system flush . Dark or brown brake fluid indicates significant contamination and the need for immediate service . It is good practice to change brake fluid every 24,000 miles or 36 months .

Brake Bleeding:

Air in brake fluid causes braking to feel spongy and reduces braking efficiency significantly. Flushing brake fluid removes existing fluid and moisture from the system and replaces it with new, clean fluid . Always use the fluid recommended by the manufacturer .

Signs of Brake Issues:

• Unusual noises (squealing or grinding)
• Vibrating pedal or steering wheel
• Burning smell coming from the tires
• Illuminated brake dashboard warning light

Spark Plug Service

The 2017 BMW 640i Gran Coupe uses spark plugs with OEM part number 12-12-0-037-582 (Bosch) .

OEM Interval:

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

Conservative Owner Guidance:

Replace spark plugs on time or about every 30,000 miles. Without the spark of electricity created by spark plugs, your engine doesn't have the combustion it needs to start, which could leave you stranded on the road .

Signs Your Engine Needs a Tune-Up:

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

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.

Wheel Alignment

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

Signs Alignment May Need Attention:

• Vehicle pulling to one side while in motion
• Rapid or uneven wear on one or more tires
• Crooked steering wheel when driving straight
• Tires that squeal frequently

You won't see any warning lights on your dashboard if your wheel alignment is off, so pay close attention to these symptoms .

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. 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 .

Differential Fluid Service

Differential oil provides lubrication and cooling for the car's differential, protecting the gears' metal surfaces from friction and preventing overheating .

Recommended Interval:

Differential oil should be changed every 30,000 to 50,000 miles . Some vehicles have a front differential and others have a rear differential, and the service requirements may differ.

BMW Maintenance Program Coverage

The recommended maintenance schedule is put together by BMW, your vehicle manufacturer . 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 .

Staying on track with routine service appointments can help your 640i Gran Coupe perform better, keep you safer on the road, and help you avoid expensive repairs caused by problems later .

Long-Term Ownership Outlook

With proactive maintenance, a 2017 BMW 640i Gran Coupe could hit 200,000 miles (or beyond!). Regular maintenance is an investment that maintains the value and dependability of your car, extends its service life, and increases its resale value.
