2016 BMW 650i xDrive Convertible Preventive Maintenance & Service Schedule

Key Takeaways

• The 2016 BMW 650i xDrive Convertible is powered by a 4.4L twin-turbo V8 engine (N63TU) and features xDrive all-wheel drive.
• A conservative synthetic oil change interval of 5,000 miles is strongly recommended by independent specialists to protect the high-performance V8 engine, significantly shorter than the BMW-recommended 10,000-mile interval .
• Major periodic service is generally recommended every 2 years or after 30,000 kilometers (approximately 18,600 miles) .
• Brake fluid should be flushed and replaced every 2 years regardless of mileage .
• The vehicle uses DOT4 specification brake fluid and Bosch spark plugs as original equipment .

Understanding BMW's Condition Based Service (CBS) System

The 2016 BMW 650i xDrive Convertible utilizes BMW's sophisticated Condition Based Service (CBS) system. Unlike traditional fixed-interval maintenance schedules, CBS uses onboard 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 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. The system monitors engine oil, brake pads (front and rear separately), brake fluid, spark plugs, microfilter, and vehicle checks.

Major Periodic Service: For major periodic service, this should generally be done every 2 years or after 30,000 kilometers (approximately 18,600 miles) .

BMW Warranty & Maintenance Coverage

The 2016 BMW 650i xDrive Convertible was covered by the following warranty packages from the original in-service date :

Projected Maintenance Costs: The scheduled maintenance program covers Years 1-3 at no cost, with Year 4 costing approximately $19 and Year 5 costing approximately $2,780 . For vehicles beyond the maintenance program coverage, owners should plan for out-of-pocket maintenance costs.

OEM & Recommended Preventive Maintenance Schedule

The following maintenance intervals represent the recommended schedule for the 2016 BMW 650i xDrive Convertible. Exact OEM 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 650i xDrive Convertible uses the N63 4.4L twin-turbo V8 engine.

Oil Specifications:

• BMW LL-01 approved synthetic oil
• Common viscosity: 5W-30 (refer to your owner's manual for climate-specific recommendations)
• Always replace the filter when changing your oil

Oil Change Interval:

Pelican Parts recommends changing your synthetic motor oil every 5,000 miles for optimal engine protection . 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 .

More frequent oil changes may be needed if you regularly:

• Haul heavy loads
• Drive in dusty conditions
• Engage in frequent short trips or aggressive driving

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

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 650i xDrive Convertible requires DOT4 specification brake fluid .

Fluid Specifications:

• DOT4 specification
• Genuine BMW low viscosity brake fluid is ideal for extreme braking conditions
• Dry Boiling Point: 280°C (536°F); Wet Boiling Point: 198°C (388°F)
• Also meets DOT 5.1, DOT 4, and DOT 3 specifications

Brake Fluid Guidance:

BMW recommends changing the brake fluid every 2 years . Brake fluid should be changed every time you service your brakes . 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.

Signs Brake Fluid Needs Attention:

• Brake fluid appears black or brown (it should be clear or light gold)
• Brake pedal feels softer or spongy
• You may have to pump the pedal for it to work properly

Spark Plug Service

The 2016 BMW 650i xDrive Convertible uses Bosch spark plugs as original equipment . The N63 V8 engine requires 8 spark plugs .

Spark Plug Specifications :

• Thread Diameter: 12 mm
• Thread Pitch: 1.25 mm
• Reach: 26.5 mm (1.04")
• Hex Size: 14 mm
• Gap: 0.028" (0.7 mm)
• Torque Specs (Aluminum): 11-15 lb. ft.

Spark Plug Guidance:

Keeping your spark plugs fresh is a very important part of keeping your car in top shape . Replacement intervals are determined by the CBS system based on actual driving conditions.

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 .

Symptoms of Spark Plug Issues:

• Misfiring
• Check Engine Light illumination
• Hesitation
• Loss of power
• Poor fuel economy

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 . It should be checked for level and changed as per the owner's manual recommendation .

Fluid Specification:

• Fully synthetic gear oil for cars 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
• Provides superior protection at high and low operating temperatures

Conservative Owner Guidance: Ensure both front and rear differentials are serviced when differential fluid is due, as the xDrive system includes both.

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 inspection of the parking brake.

Brake Pad Life: Brake pads often last between 30,000 and 40,000 miles depending on driving style and conditions. Factors like frequent highway driving and smooth braking can help brake pads last longer. Riding the brakes and hauling heavy loads can shorten their useful life.

Signs of Brake Issues:

• Unusual noises (squealing or grinding)
• Vibration or pulsation in the steering wheel or pedal
• A burning smell near the tires
• Illuminated brake dashboard warning light

Transmission Service

The 2016 650i xDrive Convertible is equipped with an 8-speed automatic transmission. BMW's original maintenance schedule classifies the transmission fluid as "lifetime fill" under normal conditions.

Conservative Owner Guidance: A conservative maintenance approach is to service the transmission as preventative maintenance at regular intervals to avoid potential failure. If left unserviced, the automatic transmission fluid will break down over time, potentially leading to poor shifting, slipping, and ultimately transmission failure. BMW recommends exchanging transmission fluids at certain intervals with BMW-approved products.

Wheel Alignment

It is generally recommended to have wheel alignment checked approximately every 6,000 miles or 6 months. Signs that alignment may need attention include:

• 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

Long-Term Ownership Outlook

With proactive maintenance, the 2016 BMW 650i xDrive Convertible can achieve high mileage. The twin-turbo V8 engine and 8-speed transmission are capable of durability with proper care. Staying on track with routine service appointments can help your 650i xDrive Convertible 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.
