2008 BMW 335xi Service and Repair Manual

This factory service and repair manual for the 2008 BMW 335xi adds a two-door coupe alongside the four-door sedan, both carrying the same turbocharged 3.0L inline-six with double overhead cams and gasoline fueling, in one trim. Because the powertrain is common to both, the engine, driveline and all-wheel-drive material is written once and applies to either car. The difference shows up in body panels, glass, trim and the harness routing behind them, which the manual documents separately for each shape.

Engines covered

• 3.0L inline-six — DOHC, turbocharged, gasoline

Body styles covered

• 4-door sedan
• 2-door coupe

Known issues on the 2008 335xi. Turbocharging puts load on parts a naturally aspirated six never sees, and the coverage reflects that: charge-air routing, boost control diagnostics, high-pressure fuel specifications, cooling system tests, and torque figures for the exhaust and turbine hardware. Outside the engine bay the manual works through the transmission and transfer case, the front and rear axles, the brakes, the suspension and steering geometry, and the wiring diagrams drawn for the sedan and the coupe as separate bodies.
