2011 BMW Z4 Service and Repair Manual

This factory service and repair manual for the 2011 BMW Z4 covers four trims — sDrive23i, sDrive30i, sDrive35i and sDrive35is — in a single two-door convertible body. Three inline-sixes are specified: a naturally aspirated 2.5L, a naturally aspirated 3.0L and a turbocharged 3.0L, all double overhead cam and all on gasoline. The turbocharged car adds boost control, charge-air ducting and its own fuel-pressure figures to the same basic architecture, which is why engine work here is organized by engine and not by model name.

Known issues on the 2011 Z4. The manual is a workshop document rather than a summary: engine mechanical work is given with clearances and torque values for each of the three sixes, fuel and ignition diagnostics are laid out with the trouble codes that lead to them, and the driveline, brake, suspension and steering sections carry their own specifications. Body coverage includes the convertible top mechanism and its drive, and the wiring diagrams run through the lighting, charging and restraint circuits with the connector views needed to test them.
