What is VW’s most reliable engine?
Tdi diesel (alh / pd): this turbocharged diesel engine is widely regarded as the gold standard for vw reliability. Produced in the late 1990s through the 2000s, it features an iron block and simple mechanical injection that contribute to its legendary longevity. Many owners consider the alh 1. Tdi (late-1990s to early-2000s) among the best. Later engines like the ea189 or ea288 can be reliable too if serviced correctly.
