2007 BMW 550i Service Requirements & Maintenance Schedule

Key Takeaways

• The 2007 BMW 550i (E60/E61 chassis) is powered by the N62 4.8L V8 engine – a naturally aspirated V8 producing approximately 360 horsepower .
• BMW utilizes a Condition Based Service (CBS) system that uses sensors and driving data to calculate maintenance needs based on actual driving conditions rather than fixed intervals .
• The vehicle features factory-specified 15,000-mile extended intervals for oil and filter changes, and 100,000-mile extended intervals for spark plugs and transmission fluid .
• Oil capacity is 8 litres with filter; recommended viscosity is 5W-30 for all temperatures .
• Spark plugs and automatic transmission fluid are scheduled for replacement at 100,000 miles .
• Oxygen sensors are scheduled for replacement at 120,000 miles .

Understanding BMW's Condition Based Service (CBS) System

The 2007 BMW 550i utilizes BMW's Condition Based Service (CBS) system, which employs sensors and special algorithms that take the different driving conditions of your BMW into account. CBS uses this to determine current and future service requirements .

CBS-Monitored Items:

• Engine oil
• Brake pads (front and rear separately)
• Brake fluid
• Vehicle check
• Legally mandated inspections depending on local regulations

Service Data Storage: Your vehicle stores the information for required maintenance continuously in the remote control during driving. After accessing the data stored in the remote control, your BMW Service Advisor can suggest precisely the right array of service procedures for your own individual vehicle .

Service Status Symbols:

• No service is currently required
• The deadline for service is approaching
• The service deadline has already passed

OEM Factory Maintenance Schedule

The following maintenance intervals are based on available documentation for the 2007 BMW 550i:

Engine Oil and Filter Change

The 2007 550i uses the N62 4.8L V8 engine, which requires high-quality synthetic oil. BMW originally specified a 15,000-mile extended service interval for oil and filter changes .

Oil Specifications:

• BMW-approved synthetic oil
• Recommended viscosity: 5W-30 (all temperatures)
• Capacity: 8 litres (approximately 8.5 quarts) with filter
• Oil Drain Plug Torque: M12x1.5 – 19 ft/lbs (consult manual for other plug variations)

Conservative Owner Guidance:

Motor oil is the single most important element in keeping your engine healthy. While BMW's original 15,000-mile interval was factory-specified for the 2007 550i , more frequent oil changes are advisable if you regularly:

• Haul heavy loads
• Drive in dusty areas
• Go off-road
• Drive at low speeds for long distances

Spark Plug Service

The N62 V8 engine uses 8 high-performance spark plugs.

Factory Interval:

BMW originally specified a 100,000-mile extended service interval for spark plugs on the 2007 550i . For other BMW engines with similar technology, BMW has recommended a 60,000-mile replacement interval for N55/N63 spark plugs .

Conservative Owner Guidance:

Some independent specialists recommend replacing spark plugs as preventative maintenance approximately every 3 years or 100,000 miles for the N62 engine . If your car begins misfiring due to old plugs, you could run into much more serious issues .

Symptoms of spark plug issues include:

• Shaking while the engine is idling
• Poor fuel economy
• Knocking noises in the engine

Brake Fluid Service

Brake fluid service is a critical safety item and is monitored by the CBS system based on time and driving conditions . Brake fluid is hygroscopic – it absorbs moisture from the atmosphere over time, which lowers its boiling point and compromises braking performance.

Conservative Guidance:

Brake fluid should typically be flushed and replaced every 2 years regardless of mileage, as recommended for most BMW vehicles .

Transmission Service

Transmission Specifications:

The 2007 BMW 550i is equipped with the ZF 6-speed automatic transmission.

Factory Claim:

BMW originally described the transmission fluid as "lifetime fill" for the 2007 550i .

Recommended Interval:

BMW recommends exchanging automatic transmission fluid at 100,000 miles . About every 30,000 to 60,000 miles is a good timeframe for having your transmission fluid inspected and perhaps changed. Service intervals can vary depending on how you use your BMW, so check with your technician first .

Oxygen Sensor Service

Factory Interval:

Oxygen sensors are scheduled for replacement at 120,000 miles . Oxygen sensors deteriorate on a mileage basis and replacement helps maximize fuel economy and minimize exhaust pollution.

BMW Factory Warranty and Maintenance Coverage

The 2007 BMW 550i was covered by a standard 4-year/50,000-mile warranty (basic and powertrain) with free scheduled maintenance for 48 months or 50,000 miles from the original in-service date .

N62 Engine-Specific Considerations

The N62 4.8L V8 engine has several known maintenance considerations that owners should be aware of as the vehicle ages .

Valve Stem Seals

A common problem with the N62 engine is increasing oil consumption due to the wear of valve stem seals. Typically, oil consumption issues start around 100,000 km (~62,000 miles), with worn valve stem seals being the main cause. After another 100,000 km, the oil control rings often fail as well .

Oil Leaks

Oil leaks are frequently reported from the generator housing gasket and crankshaft seal .

Engine Longevity

Overall, the N62 engine can last around 310,000 to 520,000 km (~193,000-323,000 miles) if properly maintained, using the correct quality oil and fuel, and carrying out regular checks and maintenance .
