2005 BMW 320i Service and Repair Manual

This factory service and repair manual for the 2005 BMW 320i documents the last of these 2.2-liter sedans: one four-door body, one Base trim, and a naturally aspirated inline-six of 132 cubic inches with double overhead camshafts, running on gasoline. Everything in the book is written for that combination, from the engine management diagnostics through to the body and interior removal steps, so the specifications quoted do not have to be filtered against other engines or trim levels first.

Engines covered

• 2.2L inline-six (132 cu in) — DOHC, naturally aspirated, gasoline

Body styles covered

• 4-door sedan

Trims covered

• Base

Known issues on the 2005 320i. One recall stands on the federal record for this model year, and it concerns the passenger frontal air bag. The propellant in the inflator can degrade after long exposure to heat and humidity, and a degraded charge can burst the inflator housing when the bag fires, throwing metal fragments into the cabin. Restraint system work is documented here with component locations, harness routing and diagnostic procedures for the air bag circuits, alongside the engine, chassis and body coverage that makes up the rest of the manual.
