Understanding BMW's Condition Based Service (CBS) System

The 2013 BMW 640i 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 Data in the Remote Control: Information on the 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. Therefore, hand your service specialist the remote control with which the vehicle was driven most recently .

Storage Periods: 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 and the microfilter/activated-charcoal filter .

Engine Specifications & Capacities

The 2013 BMW 640i Coupe is equipped with the N55 3.0L turbocharged inline-six engine (Engine Code: N55B30A) .

OEM Factory Maintenance Schedule

The following maintenance intervals represent key factory-recommended milestones for the 2013 BMW 640i Coupe. Exact intervals are determined by the vehicle's CBS system based on driving conditions.

Oxygen Sensor Service

Factory 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.

Engine Oil and Filter Change

The 2013 640i Coupe uses the N55 3.0L turbocharged inline-six engine. BMW's CBS system will indicate when an oil service is due, with typical intervals determined by driving conditions.

Oil Specifications:

• BMW LL-01 approved synthetic oil
• Oil meeting BMW LL-01 standards
• Capacity with filter: 6.5 liters

Owner Guidance: Motor oil is the single most important element in keeping your engine healthy and helping it to enjoy a long life . Independent specialists recommend changing 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 .

Brake Fluid Service

Brake fluid is a hydraulic fluid specially formulated to withstand the extreme pressures and temperatures of your braking system . The 2013 BMW 640i Coupe uses DOT4 specification brake fluid .

Owner Guidance: Brake fluid should be changed every time you service your brakes . Check your owner's manual for your vehicle's particular brake fluid specifications . BMW recommends servicing brake fluid as indicated by the CBS system.

Brake System Service

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

Brake Pad Life: Brake pads often last 30,000 to 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)
• A vibrating pedal or steering wheel
• A burning smell near your tires
• An illuminated brake dashboard warning light

Spark Plug Service

The N55 engine uses high-performance spark plugs to ignite the fuel-air mixture in the engine's combustion chamber . The 2013 BMW 640i Coupe uses Bosch spark plugs as original equipment .

Owner Guidance: Keeping your spark plugs fresh is a very important part of keeping your car in top shape . 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 . Some service providers recommend replacing spark plugs on time or about every 30,000 miles . Spark plugs should always be replaced in sets (the N55 engine uses 6 spark plugs).

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 .

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
