Reliability, common problems and owner reviews for the Suzuki SX4 1.9 DDiS (F9Q, Renault). Check this before you buy used.
The 1.9 DDiS is the Renault F9Q diesel (the same engine as the Grand Vitara DDiS and Renault Mégane dCi) — torquey and economical, but its condition is everything. Watch the F9Q's injector wear, turbo and EGR/intake sooting; it's not a bad engine, just one that punishes neglect and unknown history. A documented, oil-disciplined, motorway-driven example is dependable; an unknown urban one is a gamble — the petrol is the lower-worry choice for light use.
