Frequently asked questions
Which Volkswagen Passat B7 engine is the most reliable?
1.6 TDI 105hp (CAYC) — Maint. Sensitive verdict. The 1.6 TDI (CAYB/CAYC — the EA189-era small VAG diesel shared across the Polo/Ibiza/Fabia/Golf) is the frugal long-distance A1: genuinely economical and high-mileage capable. Standard modern-VAG-diesel cautions: DPF clogging on short trips, EGR sooting, injector wear, and the well-known electric coolant-pump and occasional timing-belt-driven-oil-pump-balance items of the era.
