2003 BMW 325Ci Service and Repair Manual

This factory service and repair manual for the 2003 BMW 325Ci opens on a short specification — one engine, the naturally aspirated 2.5L DOHC inline-six of 152 cubic inches; one trim, Base; two bodies, a two-door convertible and a two-door coupe — and spends its length on procedure rather than on variants. Engine, driveline and chassis work is written once for both cars, and the wiring diagrams separate them only where the roof, rear glass and body harness genuinely diverge.

Known issues on the 2003 325Ci. Work on this car concentrates on the six-cylinder engine and the systems wrapped around it: cooling, crankcase ventilation, fuel delivery and ignition, all with their own pressure figures, clearances and test steps. Beyond the engine bay the manual carries manual and automatic transmission procedures, driveshaft and rear axle service, suspension overhaul with alignment specifications, steering, brake hydraulics and the anti-lock system, the restraint system, and the body electrical for both shells, each with wiring diagrams and fault-tracing sequences.
