2007 BMW 525xi Service and Repair Manual

This factory service and repair manual for the 2007 BMW 525xi is written for a single configuration — one trim, one four-door sedan body, one naturally aspirated 3.0L inline-six with double overhead cams — driving all four wheels. Because there is no second engine or body in the range, the manual can be specific rather than general: figures are given as values to work to, not as ranges to interpret, and the procedures assume the transfer case and front axle this car actually has.

Engines covered

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

Trims covered

Known issues on the 2007 525xi. Coverage starts with engine mechanical work and the fuel, ignition and cooling systems that support it, each with torque values and test specifications. It continues through the transmission and driveline, the transfer case and differentials, the brake hydraulics, the suspension and steering alignment data, and the heating and air conditioning. Wiring diagrams and diagnostic routines close the book out, which is where most electrical faults on a sedan of this generation actually get solved.
