2002 BMW M3 Service and Repair Manual

This factory service and repair manual for the 2002 BMW M3 covers the convertible and the coupe together, both fitted with the 3.2L naturally aspirated inline-six and its double overhead camshafts on gasoline, both listed in Base trim. Because the two share a mechanical package, the engine, gearbox, driveline, brake, suspension and steering sections are written once and apply to either car, and the difference is handled where it actually exists, in the roof, the body structure and the wiring that runs through them.

Engines covered

• 3.2L inline-six — DOHC, naturally aspirated, gasoline

Body styles covered

• 2-door convertible
• 2-door coupe

Trims covered

• Base

Known issues on the 2002 M3. Coverage here is the practical kind. The inline-six gets its assembly specifications, torque sequences and engine management diagnostics; the fuel, ignition, cooling and emission control systems get their test procedures and pressure values; and the driveline, brakes, suspension and steering follow with the measurements a rebuild depends on. Wiring diagrams trace the lighting, charging, starting, comfort and restraint circuits through both bodies, including the roof's own controls, which is where an intermittent fault on this car often turns out to live.
