Reliability, common problems and owner reviews for the Seat Toledo IV 1.6 TDI (CAYC / CLNA). Check this before you buy used.
The 1.6 TDI is the frugal economy diesel — the EA189/EA288-family common-rail unit shared across the VW range. Slow but very economical. Watch the DPF/EGR on short trips, occasional injector wear, and the electric coolant pump. A high-mileage motorway example with good oil and DPF history is dependable and cheap to run; for town use the 1.2 TSI is the lower-hassle pick.
