Why some Volkswagen engines score below 68/100
Volkswagen's engine lineup spans some of the most reliable and some of the most problematic units in European motoring. The group's platform-sharing strategy means the same engine can appear in a Polo, a Golf, a Tiguan, and an Audi A3 — so getting the engine choice right matters across multiple brands.
The pattern
VW's reliability problems cluster around two transitions: the move from indirect to direct injection (EA111 TSI chain issues), and the diesel emissions scandal aftermath (EA189 software/hardware modifications). The pre-PD TDIs (ALH, AHF) and the latest EA888 Gen 3/4 are the sweet spots. The 2008–2014 TSI and early CR TDI units are the danger zone.
