• Original maintenance coverage included 3 years or 36,000 miles of scheduled maintenance, with a 4-year/50,000-mile basic warranty
• The S54 engine (3.2L inline-six, 315 hp) requires specialized maintenance including valve clearance adjustments—BMW recommends a 30,000-mile interval, though specialists suggest 50,000-60,000 miles is often sufficient
• Brake fluid requires replacement every 2 years; coolant is replaced every 4 years
• Spark plugs are specified for replacement every 60,000 miles for the S54 engine
• Inspection I and Inspection II are the two major factory service procedures in addition to standard Engine Oil Service

Understanding the BMW Maintenance System

The 2001 BMW M Roadster utilizes the BMW Maintenance System, which monitors actual operating conditions rather than relying solely on distance traveled to determine when service is due . The Service Interval Display (SII) shows green lights indicating remaining service life. When the final green light goes out, the vehicle indicates which service is required: Engine Oil Service, Inspection I, or Inspection II.

The system monitors fuel consumption since the last service reset to calculate when the next service is due, ensuring that maintenance timing reflects how the vehicle is actually driven .

Original Warranty and Maintenance Coverage

The 2001 BMW M Roadster was delivered with comprehensive factory coverage :

• Basic Warranty: 4 years / 50,000 miles
• Powertrain Warranty: 4 years / 50,000 miles
• Corrosion Perforation: 6 years / unlimited miles
• Roadside Assistance: 4 years / 50,000 miles
• Scheduled Maintenance: 3 years / 36,000 miles

The maintenance coverage included scheduled services as indicated by the Service Interval Display.

Factory Maintenance Schedule

Engine Oil Service

The Service Interval Indicator determines engine oil change intervals based on driving conditions. The service sequence follows a rotation: Oil Service → Inspection I → Oil Service → Inspection II → repeated.

The owner's manual emphasizes that because oil deteriorates over time regardless of use, even those who drive only short distances—significantly less than 6,000 miles annually—should have the engine oil changed regularly .

Inspection I

Inspection I is the first major service and includes:

• Engine oil and oil filter change
• Transmission leak check
• Rear axle leak check
• Visual inspection of fuel tank, lines, and connections for leaks
• Exhaust system condition and leak inspection
• Power steering system leak check and fluid level check
• Steering and suspension component inspection

Inspection II

Inspection II is the comprehensive major service and includes all Inspection I items plus:

• Replacement of intake air cleaner element (more frequently in dusty conditions)
• Replacement of spark plugs
• Replacement of transmission fluid
• Replacement of differential oil

Component-Specific Service Intervals

S54 Engine Valve Adjustment

The 2001 M Roadster is powered by the S54 3.2L inline-six engine . This engine uses solid lifters requiring periodic valve clearance inspection and adjustment. BMW recommends a 30,000-mile adjustment interval . However, specialists who regularly service S54 engines have observed that these engines tend to hold their clearances better than expected, and a 50,000-60,000-mile interval is often recommended as sufficient .

Valve adjustment requires specialized tools and shim kits and should be performed by a technician familiar with S54 engine service .

Brake Fluid

BMW specifies brake fluid replacement every 2 years regardless of mileage . The Service and Warranty Information Booklet confirms this interval. DOT 4 brake fluid meeting BMW specifications is required.

Engine Coolant

Engine coolant requires replacement every 4 years . The coolant system capacity and specification are detailed in the owner's manual .

Spark Plugs

For the S54 engine in the 2001 M Roadster, BMW recommends replacing spark plugs every 60,000 miles . The ignition service package for the S54 engine uses OEM NGK Laser Platinum spark plugs .

Oxygen Sensors

Oxygen sensor replacement is scheduled at 100,000-mile intervals according to OEM documentation .

M-Mobility System (Tire Repair Kit)

The tire inflator sealant cartridge requires replacement every 3 years .

Transmission and Differential Fluid

Transmission fluid and differential oil are replaced during Inspection II service .

Long-Term Ownership Considerations

S54 Engine Rod Bearing Awareness

Owners of early-production 2001 M Roadsters with the S54 engine should be aware of connecting rod bearing concerns that affected some early E46 M3 and Z3 M models . Early S54 engines (particularly pre-production units) have been noted to exhibit bearing shift issues. Some owners of early 2001 M Roadsters have proactively replaced connecting rod bearings as preventive maintenance .

Service Documentation

Maintaining complete service records in the Service and Warranty Information Booklet is essential for preserving vehicle value . A full service history with documented Inspection I and Inspection II services significantly enhances resale value.

Body and Corrosion Protection

BMW recommends having the body checked for damage from rocks or gravel during services. At least every two years, inspections are required to maintain the six-year limited anti-corrosion warranty .
