Audi Repair Manuals

Audi traces its roots to 1909, when August Horch founded a new car company in Zwickau, Germany, after leaving the firm that bore his name. The four rings of the Audi badge appeared in 1932, when Audi merged with DKW, Horch and Wanderer to form Auto Union. After the Second World War the company re-emerged in Ingolstadt and began using the Audi name on new models from 1965.

Audi became famous in the 1980s for the quattro all-wheel-drive system that reshaped rallying and road-car performance, and for a succession of technically advanced engines including five-cylinder turbo units, the TDI diesel family introduced at the end of that decade, and later high-performance engines developed with the quattro GmbH division. The brand is also known for aerodynamic design, aluminium space-frame construction introduced on the A8, and its long-running A3, A4, A6 and A8 model families.

Audi workshop manuals document the full engineering of each model: engines and turbochargers, fuel injection and emission systems, manual, automatic and dual-clutch gearboxes, quattro drivelines, suspension, brakes and the complete electrical architecture with wiring diagrams. Torque specifications, diagnostic procedures, adjustment data, service bulletins-style notes and scheduled maintenance intervals are all covered.

These manuals are valuable for Audi owners who service their own cars, independent European-car specialists, and professional technicians who need factory-level information for accurate diagnosis and repair of modern Audis.
