2016 BMW 340i Service and Repair Manual

This factory service and repair manual for the 2016 BMW 340i covers four trims of one four-door sedan — Base, Luxury, M Sport and Sport — all built on the same turbocharged 3.0L DOHC inline-six of 183 cubic inches. What separates those trims is suspension tuning, wheels, brakes and interior equipment rather than anything under the hood, so the fuel, ignition, cooling and emissions procedures read the same across the range, while the chassis, body and trim sections carry the specifications, torque values and wiring diagrams that do vary.

Engines covered

• 3.0L inline-six (183 cu in) — DOHC, turbocharged, gasoline

Known issues on the 2016 340i. The manual's weight sits on the turbocharged six: timing and valvetrain procedures, cooling and lubrication specifications, charge-air and fuel-delivery diagnostics, and the torque values for each of them. From there it follows the driveline rearward, then covers the brakes, steering and suspension as they are fitted to each of the four trims, and closes with body and electrical work, where the wiring diagrams are drawn circuit by circuit so a car with Luxury or M Sport equipment can be traced without guesswork.
