2008 BMW 525i Service and Repair Manual

This factory service and repair manual for the 2008 BMW 525i returns to a single specification: one four-door sedan, one Base trim, and the 2.5L inline-six of 152 cubic inches, double overhead cam and naturally aspirated on gasoline. That simplicity shows in how the book is used. There is no engine option to identify first, so a coolant capacity, a valve clearance or a wiring color read out of these pages is the right one for the car on the lift.

Engines covered

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

Body styles covered

• 4-door sedan

Trims covered

• Base

Known issues on the 2008 525i. The coverage is the ordinary work of keeping a six-cylinder sedan honest: cooling system service, timing drive and valve gear procedures, fuel and ignition diagnostics, exhaust and emissions checks, all with the specifications and torque values attached. Transmission, driveshaft and rear axle procedures follow, then steering, suspension and the hydraulic brakes. Wiring diagrams cover the charging, starting, lighting and comfort circuits, and the diagnostic material links a symptom to the test that isolates it.
