The 1.9dci 130 bhp is a FAP engine. Only special treatment required is that you give the car a decent run to get engine up to temp and burn off the soot in the FAP. A lot of short stop start journeys and the FAP filter light will come on a lot - if you don't do a decent journey the car will have to have a "forced regeneration" by a dealer. Too many of these + [email protected] catalyst.
Low annual mileag doesn't necessarily mean a problem, if the journeys you do do are decent ones. Our Megane cc is 10mths old ,only done 5k ( its our second car,not main commuter) but nearly all journeys are decent 15 mile+ runs on A roads at 60mph.
