2017 Mercedes-Benz A45 Service and Repair Manual

This factory service and repair manual for the 2017 Mercedes-Benz A45 is written for a four-door hatchback in World Champion Edition trim. Power comes from a turbocharged 2.0L inline-four running on gasoline, with double overhead camshafts, and no other engine is listed. A small displacement pushed hard by a turbocharger puts real demands on cooling, fueling and boost control, so the manual pairs that engine's specifications with procedures for the hatchback's chassis, brakes and body electrical systems.
