2016 BMW 428i Service and Repair Manual

This factory service and repair manual for the 2016 BMW 428i covers the coupe and the convertible together, both carrying the turbocharged 2.0L DOHC inline-four of 122 cubic inches, in Base, Luxury and Sport trims. Convertible-specific work — the folding roof, its mechanism, its latching and the circuits that serve it — is kept in its own part of the body section, while the engine, driveline and chassis chapters serve both bodies with the same specifications, torque values, wiring diagrams and diagnostic routines.

Known issues on the 2016 428i. The federal record carries a single recall for this year, and its subject is the cooling system: an improperly sealed connector at the water pump can let water reach the contacts and short the circuit, which raises the risk of a fire. The cooling system chapter is the one that matters there, covering pump removal and installation, connector and harness routing, coolant specifications and the torque values for the pump and its fasteners, with the wiring diagrams needed to test the circuit rather than replace parts on suspicion.
