1999 BMW 850Ci Service and Repair Manual

This factory service and repair manual for the 1999 BMW 850Ci sets out the work on a two-door coupe carrying one engine: a 5.4L V12, single overhead cam, naturally aspirated, gasoline. The trim list stops at Base. What that combination asks of a technician is method rather than variety — the same procedure performed twice, once per bank, to the same clearances and the same torque figures — and the manual prints those numbers with each procedure instead of leaving them to a general specification table.
