Reliability, common problems and owner reviews for the Volkswagen Touran 1.6 TDI 105hp (CAYC). Check this before you buy used.
The 1.6 TDI common-rail (CAYC, EA189) is the later economy diesel — frugal and refined, the same unit as Golf VI/Polo/Octavia. Main watch items are the DPF/EGR on short trips and occasional injector or coolant-pump (electric aux pump) niggles. A bit slow in the MPV, but a high-mileage motorway example with good oil history is dependable and very economical.
