Reliability, common problems and owner reviews for the Nissan Micra 1.2 DIG-S supercharged (HR12DDR). Check this before you buy used.
The DIG-S adds a supercharger and direct injection to the 1.2 three-cylinder for more poke and good economy — but more complexity. Watch for higher oil consumption on some units, direct-injection carbon build-up on the intake valves, and the usual chain-tension discipline. Rewarding and economical when healthy, but a neglected one costs more than the plain 1.2; check oil level and history carefully.
