Reliability, common problems and owner reviews for the Volkswagen Passat B7 1.6 TDI (CAYC). Check this before you buy used.
The 1.6 TDI (CAYC, EA189) is the economy diesel — frugal and refined, the same unit as Golf VI/Octavia. Slow in the big Passat but very economical. Watch the DPF/EGR on short trips and occasional injector or electric coolant-pump niggles. A high-mileage motorway example with good oil history is dependable and cheap to run.
