2018 BMW 430i xDrive Gran Coupe Service and Repair Manual

This factory service and repair manual for the 2018 BMW 430i xDrive Gran Coupe describes a car with four doors and a hatch rather than a trunk lid, sold in one Base trim, with a single engine underneath: a 122-cubic-inch 2.0L inline-four, turbocharged, double overhead cam, gasoline. Because the car comes in one configuration, the book never hedges. Engine, driveline, chassis and body procedures are given with the specifications, torque values, wiring diagrams and diagnostics that belong to this exact vehicle.

Trims covered

Known issues on the 2018 430i xDrive Gran Coupe. Most of the work this manual gets used for is routine until it is not: a coolant loss that has to be traced rather than topped up, an intake or exhaust joint that needs the printed torque instead of an educated guess, a suspension refresh that only holds its alignment if the specifications are followed. The engine chapters cover fuel, ignition, cooling, lubrication and emissions for the turbocharged four, the chassis chapters cover brakes, steering, suspension and driveline, and the diagnostics tie symptoms back to circuits and components.
