2000 BMW M5 (E39) Service Schedule & Maintenance Guide

Key Takeaways

• The 2000 BMW M5 requires a specialized S62 engine oil level check procedure—the engine must be at full operating temperature, idled for at least 15 seconds, turned off, and then allowed to drain for at least 1 minute before checking the dipstick . This precise procedure must be followed to get an accurate reading.
• Independent specialists recommend oil changes every 5,000–10,000 miles, depending on driving habits, with performance-driven vehicles benefiting from the shorter interval .
• Brake fluid flushes are scheduled at 30,000-mile or 2-year intervals (whichever comes first), with a full brake inspection recommended at least every 12,000 miles or 12 months .
• Engine coolant and the tire inflator sealant cartridge have scheduled replacements at 45,000-mile or 36-month intervals .
• The S62 V8 has known weak points including timing chain guides, carbon buildup in the secondary air injection system, and valve cover gasket leaks—proactive inspection is essential .
• The BMW factory maintenance program for this era covered 4 years or 50,000 miles from the original in-service date .

Understanding BMW's Condition Based Service (CBS) System

The 2000 BMW M5 uses BMW's Condition Based Service (CBS) system, which monitors actual driving conditions to determine maintenance intervals rather than following a rigid schedule . The system takes into account how the vehicle is driven—62,000 miles accumulated in short-distance urban driving are not equivalent to the same distance covered at moderate speeds on highways.

Service notifications appear via a gauge in the instrument cluster with a series of green lights that gradually extinguish as the service interval approaches . When the last green light goes out, an "Oil Service" or "Inspection" notification appears. The system factors in fuel consumption, engine load, and driving conditions—a car driven hard will require service sooner than one driven gently.

BMW recommends that if you drive significantly less than 6,200 miles annually, you should have the engine oil changed at least every 2 years, as oil deteriorates over time regardless of use. BMW's maintenance guidelines are sensor-driven, utilizing electronic oil measurement to monitor the engine load on the current oil fill based on driving style and distances, displayed on the vehicle's Control Display .

BMW Factory Maintenance Program

The 2000 BMW M5 was covered under BMW's factory maintenance program, which offered complimentary scheduled maintenance during the first 4 years or 50,000 miles from the vehicle's original in-service date . This coverage included:

• Engine oil and filter changes
• Brake fluid flushes
• Spark plug replacements
• Vehicle checks

The vehicle carried a standard 4-year/50,000-mile new vehicle warranty.

A 60,000-mile major service includes all 30,000-mile items plus:

• Spark plug replacement
• Ignition coil and coil boot inspection and replacement
• Replacement of belt roller pulleys and belt tensioners

Engine Oil Service

Special S62 Oil Level Checking Procedure

The S62 engine in the 2000 M5 requires a different procedure than conventional practice to check the oil level. This procedure must be followed precisely for a true indication of the oil fill level :

1. The engine must first be at full operating temperature
2. Let the engine idle for at least 15 seconds
3. Turn the engine off
4. Wait at least 1 minute for the oil to drain down into the sump
5. Check the level using the dipstick

Important Warnings:

• The oil volume between the two marks on the dipstick corresponds to approximately 1.1 US quarts (1 liter)
• Do not fill beyond the upper mark on the dipstick—excess oil will damage the engine
• Wait until the level has dropped to just above the lower mark before adding oil
• Never let the oil drop below the lower mark

Oil Specifications

The S62 V8 engine requires BMW-approved synthetic oil . Recommended options include:

• OE BMW 5W-30
• BMW-Castrol 10W-60
• Motul
• Liqui Moly Longtime High Tech 5W-30
• Liqui Moly Race Tech GT1

Signs an Oil Change is Needed Sooner

Signs that an oil change may be needed sooner than the CBS indicator suggests include :

• Check engine/oil change light is on
• Engine knocking sounds
• Oil smell inside the vehicle
• Excess amount of vehicle exhaust
• Frequent dusty road driving, heavy loads, or low-speed driving for long distances

Spark Plugs

BMW technicians will change the spark plugs every 60,000 miles according to general factory maintenance schedules . Independent specialists recommend spark plug replacement as part of the 60,000-mile major service, along with ignition coil and coil boot inspection.

Brake Fluid & Brake Inspection

Brake Fluid Schedule

Brake fluid should be flushed and bled at 30,000-mile or 24-month intervals (whichever comes first), then repeated according to the OEM schedule . Brake fluid is hygroscopic—it absorbs moisture over time, which lowers its boiling point and can lead to brake fade.

Brake Inspection Schedule

BMW generally recommends that rear and front brakes be removed and serviced at least once every 12,000 miles or 12 months . This includes:

• Inspecting brake pads (replace when material reaches approximately 3mm)
• Inspecting brake rotors for scoring, wear, or warping
• Checking the parking brake operation
• Inspecting brake lines and calipers

Signs of brake problems include :

• Unusual sounds from the brakes
• Vibration or pulsation in the pedal or steering wheel
• Burning smell around the tires
• Dashboard brake light illuminated
• A sensation that braking performance has changed

Brake Pad Lifespan: The majority of brake pads last between 30,000 and 40,000 miles, depending on driving style and terrain . Highway driving and smooth braking extend pad life, while heavy loads or frequent hard braking reduce it.

Cooling System

OEM documentation specifies coolant flushes at 45,000-mile or 36-month intervals . The S62's thermostat is calibrated to 79 degrees Celsius—lower than many vehicles, which can be problematic because condensation burns off at 100°C . Ensuring the cooling system functions correctly is essential.

Regular monitoring of coolant levels is recommended, and any signs of coolant leaks should be addressed promptly.

Engine Air Filter & Fuel Filter

• Engine Air Filter: BMW technicians will change the engine air filter every 60,000 miles
• Fuel Filter: Fuel filters are typically changed every 20,000 to 40,000 miles according to general BMW maintenance guidelines

Oxygen Sensors

OEM documentation specifies oxygen (O2) sensor replacement at 100,000 miles, then again at 200,000 miles . A failing oxygen sensor can harm performance and fuel mileage and affect drivability.

Known S62 Engine Weak Points (High-Mileage Considerations)

Timing Chain Guides

Failed timing chain guides are a notorious failure point on the S62 engine . A teardown of a 140,000-mile S62 engine showed failed timing chain guides as a primary cause of engine failure. Proactive inspection and replacement are recommended on higher-mileage examples.

Carbon Build-Up (Secondary Air Injection System)

The S62 engine's secondary air injection system is prone to carbon build-up, which is impossible to clean without removing the cylinder head . Regular maintenance and inspection of this system are recommended.

Valve Cover Gaskets

The valve cover gaskets are common leak points on the S62 engine, particularly on older, higher-mileage examples . A teardown of a 140,000-mile S62 engine showed the valve cover gasket appeared to be original to the car.

Additional Maintenance Considerations

Specialists recommend checking or replacing the following on higher-mileage E39 M5s:

• Fuel pump (especially if the car is hard to start or stumbles in the RPM range)
• Front (pre-cat) oxygen sensors
• Valve cover gaskets, intake plenum seals, vacuum lines, and hoses for leaks
• Crankcase vent valve/oil separator system
• VANOS solenoid rebuild or replacement
• Camshaft position sensors
• Secondary air pump system test or service
