2015 BMW 435i Gran Coupe Service and Repair Manual

This factory service and repair manual for the 2015 BMW 435i Gran Coupe steps up from four cylinders to six: a turbocharged 3.0L inline-six with double overhead camshafts, gasoline, in a four-door hatchback offered as Base or M Sport. The two trims share the drivetrain, so the engine and driveline data reads the same for both. What varies is equipment, and the manual keeps that distinction visible in its wiring diagrams and body sections rather than burying it.

Engines covered

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

Body styles covered

Trims covered

Known issues on the 2015 435i Gran Coupe. The six-cylinder gets the detail a forced-induction engine needs — timing chain procedure, valvetrain clearances, turbocharger and charge-air specifications, high-pressure fuel values, cooling system tests and the torque sequences that hold it together. From there the manual documents the transmission and rear axle, the brake hydraulics, the suspension geometry and steering, the heating and air conditioning, and the body electrics of a hatchback whose rear harness runs through a hinged tailgate.
