2002 BMW 525i Service and Repair Manual

This factory service and repair manual for the 2002 BMW 525i covers a car sold in two shapes on one drivetrain: a four-door sedan and a four-door wagon, both carrying the naturally aspirated 2.5L inline-six of 152 cubic inches, with double overhead camshafts and gasoline fueling. A single Base trim keeps the equipment list short, so most of what separates one car from the next is body hardware rather than driveline, and the sections follow that split, taking the engine and driveline first and the two bodies afterward.

Engines covered

• 2.5L inline-six (152 cu in) — DOHC, naturally aspirated, gasoline

Body styles covered

Known issues on the 2002 525i. What this manual gives a technician is the specification side of the job: procedures, torque values, clearances and diagnostics for the 2.5L inline-six, its fuel and ignition management, the cooling system and the exhaust and emissions hardware. Wiring diagrams cover the body electrical system for both the sedan and the wagon bodies. Brakes, steering, suspension, the transmission and the final drive each carry their own procedures and specifications rather than a shared summary chapter.
