Understanding BMW's Condition Based Service (CBS) System

The 2013 BMW 740Li xDrive utilizes BMW's Condition Based Service (CBS) system, which adapts maintenance requirements based on actual driving conditions rather than fixed schedules . The system uses sensors and algorithms that take into account the driving conditions of your vehicle to determine when maintenance is required, considering factors such as trip length, engine temperature, and driving style.

Service information on required maintenance is stored in the vehicle's remote key fob. Your BMW Service Advisor can read this data to propose the precise maintenance procedures needed for your vehicle based on your specific driving patterns .

The recommended maintenance schedule is established by BMW, and scheduled maintenance services can vary depending on driving conditions, climate, and other factors . Staying on track with routine service appointments is one of the best ways to help extend your 740Li xDrive's life and increase your vehicle safety .

OEM Factory Maintenance Schedule

The following maintenance intervals represent the key factory-recommended milestones for the 2013 BMW 740Li xDrive. 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 2013 740Li xDrive uses the N55 3.0L turbocharged inline-six engine with an oil capacity of approximately 6.5 liters .

Oil Specifications:

• BMW has identified either synthetic or conventional as the ideal oil for your 2013 740Li xDrive
• Always replace the oil filter when changing your oil
• Approved oil kits for the N55 engine include 7 liters of fully synthetic oil

Oil Change Interval Guidance:

BMW recommends having your 2013 740Li xDrive's motor oil changed at regular intervals . Your 740Li xDrive may need an oil change sooner if:

• The check engine light is on
• You hear knocking sounds from the engine
• You sense an oil smell in the cabin
• You see an excess amount of vehicle exhaust

More frequent oil changes may be needed if you regularly haul heavy loads, drive in dusty conditions, 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 an opportunity to diagnose and treat other issues, such as worn brake pads or a failing battery .

Estimated Service Cost: A typical oil change for the 2013 BMW 740Li xDrive at a professional service center is estimated at approximately $268–$384, depending on location and shop rates . Prices include parts and labor and may vary by region.

Spark Plug Service

The 2013 BMW 740Li xDrive uses Bosch spark plugs as original equipment, and the N55 engine requires 6 spark plugs . Bosch is a leading global supplier of automotive components and systems known for high-quality products with a strong reputation for reliability, durability, and performance .

Spark Plug Options:

• Bosch OE High Power spark plugs
• NGK ILZKR7B-11S
• Bosch FR7NPP332

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

Symptoms of Faulty Spark Plugs :

• Engine misfires — the engine will not operate smoothly, leading to a lack of power and acceleration
• Poor fuel economy — incomplete combustion leads to wasted fuel
• Hard starting — the spark plug is responsible for igniting the fuel in the engine to start the car
• Engine vibration — can be especially noticeable at idle or when accelerating
• Rough idling — the engine runs unevenly, feeling rough or choppy
• Reduced power — lack of acceleration or sluggishness when driving
• Check engine light — the vehicle's computer can detect problems with the spark plugs and trigger the check engine light

Replacing spark plugs on time or about every 30,000 miles is recommended to maintain peak engine performance . Spark plugs should always be replaced in sets .

Estimated Service Cost: A spark plug replacement for the 2013 BMW 740Li xDrive is estimated at approximately $384–$552 at a professional service center, with parts costing approximately $76 and labor approximately $210–$350 depending on location .

Oxygen Sensor Service

Oxygen sensors are scheduled for replacement at 120,000 miles, with a repeat service at 150,000 miles . 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 2013 BMW 740Li xDrive uses DOT4 specification brake fluid .

Fluid Guidance: Brake fluid should be changed every time you service your brakes . Different brake systems require different brake fluid formulations—check your owner's manual for your vehicle's particular brake fluid specifications. Brake fluid is hygroscopic—it absorbs moisture from the atmosphere over time, which lowers its boiling point and compromises braking performance.

Brake System Service

BMW generally recommends that at a minimum, front and rear brakes are removed and serviced at least once every 12 months or 12,000 miles, including inspection of 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. If you often haul heavy loads or ride your brakes, your brake pads may wear out sooner .

Symptoms 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
• A sensation that something isn't right

Differential Fluid Service

The xDrive all-wheel-drive system includes both front and rear differentials. Differential oil lubricates and assists in the heat dissipation of the differential and 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. It provides superior protection at high and low operating temperatures where conventional oils can't, extending component life span .

Wheel Alignment

It is generally recommended to have wheel alignment checked approximately every 6,000 miles or 6 months, whichever comes first . Even a small misalignment can decrease fuel efficiency and over time can lead to premature wear and tear on your vehicle .

Signs Alignment May Need Attention :

• A feeling that your car pulls to one side
• Rapid or uneven tire wear
• A steering wheel that feels off center or crooked while driving straight
• Tires that squeal frequently

Unlike with other potential issues, you won't see any dashboard warning lights in your 740Li xDrive if your wheel alignment needs attention .

Engine Tune-Up Signs

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

• Decreased gas mileage
• "Rough" idling or stalling when stopped
• Knocking noises in the engine
• A lit check engine light on your dashboard

Periodic tune-ups can bring power back to your 740Li xDrive's engine, helping it start smoothly and run more efficiently, which can mean better fuel economy and lower emissions .

Long-Term Ownership Outlook

With proper and diligent maintenance, a 2013 BMW 740Li xDrive could be on the road well past the 200,000 mile mark . Staying on track with routine service appointments can help your 740Li xDrive perform better, increase your vehicle safety, 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. Good maintenance should never be viewed as an expense—it is an investment in the longevity and reliability of your BMW.
