The Audi 80 was produced by Audi, the German manufacturer founded by August Horch in 1909 and later based at Ingolstadt, and it played a central role in the company's modern success. Built from 1972 to 1995 across four generations, the model established Audi as a serious contender in the European mid-size saloon market and introduced generations of drivers to the brand's engineering quality.

Early Audi 80 models arrived just before the fuel crises of the 1970s and were praised for their durable engines, solid bodies and refined road manners, quickly becoming one of Europe's most popular family cars. Later generations brought ever more advanced engineering, including fuel-injected petrol engines, economical diesel and turbo-diesel versions, and progressively better safety and corrosion protection. The model's reputation helped build the premium image that Audi enjoys to this day.

Workshop manuals for the Audi 80 cover the complete car, with emphasis on its engines: timing and valve-train data, fuel and ignition systems, cooling and lubrication, and turbocharger and injection service where fitted. They also document manual and automatic gearboxes, suspension and steering, brakes, and the complete electrical system with wiring diagrams. Torque specifications, adjustment values, diagnostic procedures and scheduled maintenance schedules are all included.

These manuals serve private owners who maintain their own cars, independent garages that work on older German saloons, and enthusiasts restoring early Audi 80s, all of whom need accurate factory information for these long-lived vehicles.
