Problematic

Reliability, common problems and owner reviews for the Citroen C5 1.6 HDi (DV6). Check this before you buy used.

The 1.6 HDi (DV6) — economical but underpowered for a car the size of the C5, and prone to turbo oil starvation: the narrow oil-feed pipe carbons up if oil changes are delayed or the wrong oil used, seizing the turbo. DPF clogs on short urban trips. The dipstick-tube quirk (plastic tip snapping into the sump) carries over too. Only sensible with strict oil discipline and motorway use — the 2.0 HDi is the far better C5 diesel.
