1982 BMW 320i Service and Repair Manual

This factory service and repair manual for the 1982 BMW 320i documents a mechanically plain car: a 1.8-liter single-overhead-cam inline-four of 107 cubic inches, naturally aspirated and running on gasoline, in a two-door coupe body with one Base specification. Work on a car of this age is largely mechanical and electrical rather than software-driven, and the manual is written that way, with adjustment figures, clearances, torque values and circuit diagrams a technician can follow using hand tools and a multimeter.

Known issues on the 1982 320i. One owner complaint is logged with NHTSA for this model year, and it concerns the electrical system. That is well covered here: wiring diagrams for the whole car, connector and ground locations, and diagnostic steps for charging, starting, lighting and instrument faults, which are the circuits most likely to give trouble on a car of this vintage. The mechanical sections carry engine overhaul specifications for the four, along with fuel, ignition and valve adjustment figures, brake and suspension repair, and driveline service.
