Understanding BMW's Condition Based Service (CBS) System

The 2017 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.

Important Note on Oil Service Interval: BMW issued a service action for N63 and N63TU engine-equipped vehicles to set the CBS oil service interval to 12 months/10,000 miles. This update assures engine longevity by ensuring more frequent oil changes . This applies to N63 engines produced from 6/2008 through 6/2014 and N63TU vehicles produced from 07/2012 to 07/2013 .

BMW Warranty & Maintenance Coverage

The 2017 BMW 650i xDrive Convertible was covered by the following warranty packages from the original in-service date:

For vehicles beyond the scheduled maintenance coverage period, owners should plan for out-of-pocket maintenance costs.

OEM Factory Maintenance Schedule

The following maintenance intervals represent key factory-recommended milestones for the 2017 BMW 650i xDrive Convertible :

Engine Oil and Filter Change

Motor oil is the single most important element in keeping your N63 V8 engine healthy and helping it to enjoy a long life. The 2017 650i xDrive Convertible uses the N63 4.4L twin-turbo V8 engine, which generates significant heat and requires diligent maintenance.

Oil Specifications:

• BMW Longlife-01 (LL-01) approved synthetic oil
• BMW recommends Castrol, Liqui Moly, or other brands meeting BMW LL-01 approval
• Common viscosity: SAE 5W-30 (refer to your owner's manual for climate-specific recommendations)
• Always replace the oil filter when changing your oil

Oil Change Guidance:

BMW has specified a reduced oil service interval of 12 months/10,000 miles for the N63 engine through a Service Action . However, independent specialists strongly recommend changing your synthetic motor oil every 5,000 miles for optimal engine protection.

More frequent oil changes are advisable 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

Spark Plug Service

The 2017 BMW 650i xDrive Convertible uses Bosch spark plugs (BMW part #12-12-0-040-581, ZR5TPP330A) as original equipment . The N63 V8 engine requires 8 spark plugs .

Spark Plug Specifications:

• Thread Size: 12x1.25mm
• Reach: 26.5mm
• Hex Size: 14mm
• Gap: .031" (.8mm) or .028" (0.7mm) depending on variant
• Torque Specs: 23 ± 3 Nm (~17 ft-lb) or 11-15 lb. ft. for aluminum
• Bosch platinum center electrode heat-fused into ceramic insulator for longer service life

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

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.

Symptoms of Spark Plug Issues:

• Misfiring
• Check Engine Light
• Hesitation
• Loss of Power
• Poor Fuel Economy

Oxygen Sensor Service

OEM Interval: 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 essential for the operation of your car's brakes. Over time, brake fluid absorbs air, moisture, sludge, and other contaminants . A brake system flush removes existing fluid and moisture from the system and replaces it with new, clean fluid .

Fluid Guidance: If you've noticed that your brake fluid appears black or brown, it's well past time for a service . In a normal system, the brake fluid is clear or very light gold in color. Very dark colors indicate significant contamination and moisture absorption, which reduces the system's ability to build pressure and compromises braking performance .

Our recommendation: It is a good practice to change brake fluid every 24,000 miles or 36 months . Always use a fluid recommended by your vehicle manufacturer .

Signs Brake Fluid Needs Attention:

• Brake fluid appears black or brown
• Brake pedal feels softer or spongy
• You may have to pump the pedal a couple of times for it to work properly

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 2017 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.

Differential Fluid Service

The xDrive all-wheel-drive system includes both front and rear differentials. The N63 V8 engine-powered vehicle requires fully synthetic gear oil for standard differentials .

Fluid Specification:

• Fully synthetic gear oil
• Genuine BMW 75W-90 full synthetic final drive lubricant is specially designed for use in BMW final drives
• Provides superior protection at high and low operating temperatures
• xDrive includes both front and rear differentials; ensure both are serviced when differential fluid is due

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. Short trips and extreme temperatures can shorten the overall life expectancy of your BMW 650i xDrive Convertible battery.

Long-Term Ownership Outlook

With proactive maintenance, the 2017 BMW 650i xDrive Convertible can achieve high mileage. The N63 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.
