Reliability, common problems and owner reviews for the Citroen C5 2.0 HDi (DW10). Check this before you buy used.

The 2.0 HDi (DW10, 138–163hp) is the engine to buy in the X7 — the taxi-driver's choice, regularly reaching 200,000+ miles on regular oil and motorway-supported DPF regens. Known niggles: a glow-plug relay that can fail and burn out multiple plugs, repeat EGR-valve failures (often from low-rev city driving), and throttle-butterfly sticking causing limp mode. Strong and economical with maintenance.
