2002 BMW 330i Service and Repair Manual

This factory service and repair manual for the 2002 BMW 330i deals with a single specification of car: the four-door sedan in Base trim, powered by a naturally aspirated 3.0L inline-six with double overhead camshafts and gasoline fueling. One engine and one body make the book a reference rather than a catalog. A value looked up applies to the car being worked on, and the sections move from engine mechanical work outward through the driveline and chassis to the body and its wiring.

Engines covered

• 3.0L inline-six — DOHC, naturally aspirated, gasoline

Trims covered

Known issues on the 2002 330i. Coverage begins at the inline-six: timing drive, cylinder head and valve gear, lubrication, cooling, fuel supply, ignition and emissions control, each with the clearances and torque values the work requires. It continues into the transmission, driveshaft and rear axle, then the steering, suspension and hydraulic brakes. Wiring diagrams cover charging, starting, lighting and interior circuits, and the diagnostic sections take a symptom through the tests that identify its cause.
