2008 BMW 335i Service and Repair Manual

This factory service and repair manual for the 2008 BMW 335i has two trims and three bodies over a single engine. Base and M Sport cars share the turbocharged 3.0-liter inline-six, double overhead camshafts, gasoline, whether the body is a four-door sedan, a two-door convertible or a two-door coupe. The mechanical sections therefore run once and apply throughout, while the differences the trims and bodies introduce show up in the specifications, the fastener torques and the wiring diagrams.

Known issues on the 2008 335i. Diagnosis on a forced-induction car depends on knowing what a correct reading looks like, and the manual gives those values, from fuel pressures and sensor outputs to charge air and cooling figures, alongside the procedures for taking them. Engine mechanical work is covered from routine service through cylinder head and timing component removal. The driveline, brake and suspension sections give their own limits and torques, and the wiring diagrams trace each circuit from its distribution point to the load for sedan, coupe and convertible alike.
