The Volkswagen Golf IV (Type 1J) marked a major turning point in the history of the compact car category. Upon its release, it redefined the standards of finish and perceived quality, bordering on the premium segment thanks to rich materials and rigorous assembly. Mechanically, it is famous for having democratized and pushed direct injection diesel technology to its peak, first with distributor pump (VP37), then with the formidable Unit Injector (TDI IP) technology. Although its road handling is often judged too placid (soft suspensions favoring comfort at the expense of dynamism), it remains an icon of mechanical reliability if maintenance is respected. Today, it is a prized 'youngtimer', particularly in its TDI 130/150 variants and its sporty versions (GTI, V6, R32).
The Volkswagen Golf IV is a monument of the modern automotive era. If you are looking for an economical and indestructible 'daily driver', the 1.9 TDI 90 hp (ALH/AGR) with a rotary pump is the safest and least expensive choice for maintenance. For road use combining first-class performance and ridiculous fuel consumption, the 1.9 TDI 130 hp (ASZ) is the absolute best buy, provided the maintenance history is scrupulously checked (505.01 oil, timing belt, dual-mass flywheel). Avoid entry-level gasoline engines (1.4 16v) and the first-generation TDI 115. Despite its minor electrical flaws and interior plastics that age poorly, a well-maintained Golf IV TDI can easily exceed 400,000 km.
