2006 BMW 330i Service and Repair Manual

This factory service and repair manual for the 2006 BMW 330i covers the Base four-door sedan and the 3.0L inline-six that powers it, a naturally aspirated, double-overhead-cam gasoline engine. A single specification through the whole book means the technical material can be detailed instead of conditional: torque values without footnotes about which version they apply to, wiring diagrams for one body, and diagnostics written for one engine management arrangement rather than several.

Engines covered

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

Body styles covered

• 4-door sedan

Trims covered

• Base

Known issues on the 2006 330i. Cooling and lubrication are where an inline-six of this kind asks for attention, and both are specified here in detail: coolant routing and capacities, thermostat and pump service, oil pressure figures, and the torque values for the covers and housings that get disturbed along the way. Fuel, ignition and emissions diagnostics follow, then the transmission, driveshaft and rear axle, the steering, suspension and brakes, and the wiring diagrams and fault-tracing procedures for the sedan's electrical circuits.
