The Volkswagen Golf () is a compact car/small family car (C-segment) produced by the German automotive manufacturer Volkswagen since 1974, marketed worldwide across eight generations, in various body configurations and under various nameplates – including as the Volkswagen Rabbit in the United States and Canada (Mk1 and Mk5), and as the Volkswagen Caribe in Mexico (Mk1). The Golf is Volkswagen's best-selling model and the third best-selling automobile of all time, with over 37 million units sold worldwide. The original Golf Mk1 was a front-engined, front-wheel drive replacement for the air-cooled, rear-engined, rear-wheel drive Volkswagen Beetle. Initially, most Golfs were hatchbacks, with the three-door version being somewhat more popular than the five-door. Other variants include an estate (Variant, from 1993), convertible (Cabriolet or Cabrio, from 1979), and a Golf-based saloon called the Jetta, Vento (from 1992), or Bora (from 1999). The Golf covers economy to high-performance market segments. The Golf has won awards, including the World Car of the Year in 2009, with the Mk6 and in 2013 with the Mk7. For practical service on Golf, this matters because generation and configuration differences directly affect diagnostics, coding options, and error interpretation.
