2005 BMW 330Ci Service and Repair Manual

This factory service and repair manual for the 2005 BMW 330Ci covers two trims, Base and M, in a two-door coupe and a two-door convertible, all of them with the naturally aspirated 3.0L DOHC inline-six. The engine is common to every combination, so the differences between the four cars show up in chassis hardware, seating and trim rather than under the hood, and those are handled in the suspension and body sections with their own specifications and torque values.

Engines covered

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

Body styles covered

• 2-door coupe
• 2-door convertible

Trims covered

Known issues on the 2005 330Ci. Air bag inflators account for two entries on this car's federal record. One is a passenger-side unit whose propellant degrades after long exposure to humidity and heat, so the inflator can burst and scatter metal fragments when it fires; the other is a driver's-side unit that can rupture the same way on deployment. A third entry covers a replacement brake master cylinder sold for these cars, on which the seal can fail and leak fluid until braking performance drops away. The manual covers restraint work and the brake hydraulic system alike.
