Reliability, common problems and owner reviews for the Opel Mokka 1.6 / 1.7 CDTI (diesel). Check this before you buy used.
The CDTI diesels suit the Mokka's weight well — the 1.7 CDTI (Fiat-GM-derived) and the later 1.6 CDTI ('Whisper') are torquey and economical, with AWD available. Standard modern-diesel cautions: DPF clogging on short trips, EGR sooting, injector wear, and the 1.6 CDTI in particular wants attention to its DPF/emissions hardware on urban use. A documented, motorway-driven example is a dependable, well-matched SUV diesel; buy on oil and DPF history.
