The DW started with an SOHC 2-valve design between 2.0 and 2.0 L (1,968 and 1,997 cc), later receiving DOHC and four valves per cylinder upon the introduction of the 2.2 L in 2000 with the Citroën C5 and Peugeot 607. Turbocharged versions started using common rail and received the commercial designation HDi.
The 110 has more pipes under the bonnet, so thats an easier way to tell too. Also, both of our C5s has a sticker on the B pillar in the door shut on the drivers side, which says 2.0HDi 110bhp. Check for that. The earlier 2.0HDi (both 90 & 110) does not have a FAP filter, therefore no Eolys fluid.
