1994 BMW 850CSi Service and Repair Manual

This factory service and repair manual for the 1994 BMW 850CSi covers a two-door coupe with a 5.6L V12 under a very long hood — a single overhead camshaft per bank, naturally aspirated, gasoline — in a single trim. Twelve cylinders means two of nearly everything: two banks to time, two sets of clearances to check, paired fuel and ignition management to test against each other. The manual is organized so that symmetry is explicit rather than assumed.

Known issues on the 1994 850CSi. Engine coverage carries the specifications, torque sequences and timing procedures for both cylinder banks, plus the fuel, ignition and cooling data a large V12 depends on. The manual then documents the transmission and rear axle, the brake hydraulics, the suspension and steering geometry, the heating and air conditioning, and the coupe's body electrics. The wiring diagrams are the part most often needed on a car of this complexity, and they trace circuits through the whole shell.
