2010 BMW 335i Service and Repair Manual

This factory service and repair manual for the 2010 BMW 335i covers a car sold in three shapes off one drivetrain: a four-door sedan, a two-door convertible and a two-door coupe, each carrying the turbocharged 3.0L DOHC inline-six on gasoline. Two trims, Base and M Sport, separate the equipment rather than the mechanicals, so the engine, driveline and chassis sections apply straight across the range, while the wiring diagrams account for what the M Sport package adds and where it ties into the car.

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

Body styles covered

• 4-door sedan
• 2-door convertible
• 2-door coupe

Known issues on the 2010 335i. The engine section is built around the turbocharged 3.0L inline-six — fuel delivery under boost, ignition, cooling and the charge-air plumbing that comes with forced induction — with torque values and clearances given for that unit alone. From there the manual works outward: transmission and driveline procedures, brake and suspension specifications, steering geometry, and wiring diagrams that take in the convertible's roof structure alongside the body circuits shared by all three shells. Diagnostic routines are keyed to the systems as fitted.
