Reliability, common problems and owner reviews for the Dacia Dokker / Lodgy 1.6 (K7M / K4M). Check this before you buy used.
The 1.6 petrols (8-valve K7M, 16-valve K4M) are the simple, cheap-to-run Dacia engines — proven Renault units, dependable and easy to fix, but underpowered hauling a loaded van/MPV. The K7M 8v is the most basic and tough; the K4M 16v is a little livelier (and belt-driven/interference, so cam-belt discipline matters). Fine for light duties; most buyers wanting torque pick the 1.5 dCi. Keep the belt and ignition in check and they just run.
