Reliability, common problems and owner reviews for the Ford Fiesta Mk7 1.4 / 1.6 TDCi (PSA DV4 / DV6). Check this before you buy used.

The TDCi diesels are PSA units (the 1.6 is the same DV6 used in Peugeot/Citroën/Ford across the range) — very economical and high-mileage capable, but with the DV6's signature turbo oil-starvation risk: the narrow oil-feed pipe carbons up if oil changes are stretched, seizing the turbo. DPF clogging on short trips too. Only makes sense for high motorway mileage and with strict oil discipline; the petrols are lower-worry for ordinary use.
