2001 BMW 330i Service and Repair Manual

This factory service and repair manual for the 2001 BMW 330i covers a four-door sedan in Base trim with one engine: the 3.0L inline-six, double overhead camshafts, naturally aspirated, running on gasoline. There is no second displacement and no second body to work around, which puts all the weight of the book on depth rather than breadth, taking in engine mechanical work, fuel and ignition management, cooling, driveline, chassis and the body electrical system, each with its own specifications and torque values.

Engines covered

Body styles covered

• 4-door sedan

Trims covered

• Base

Known issues on the 2001 330i. Eight recalls stand against this year. Several concern frontal air bag inflators: one design absorbs moisture and can burst or underinflate the bag, another builds excessive internal pressure and ruptures, either way sending fragments at the occupants. One covers the engine cooling fan, where a failing fan motor overloads the control unit until cooling stops and the unit itself can catch fire. Another covers wheel rims whose inner flange was damaged at assembly, allowing sudden pressure loss. Owners logged 121 complaints, 35 on air bags, 22 on the power train and 13 on the electrical system.
