Reliability, common problems and owner reviews for the Peugeot 407 1.6 HDi (DV6). Check this before you buy used.
The 1.6 HDi (DV6) — economical but prone to turbo oil starvation: the narrow oil feed lines block with carbon if oil changes are delayed or poor oil used, seizing the turbo. (Also a known quirk: the plastic dipstick end can snap off into the sump.) Plus DPF on short trips. Only sensible with strict oil discipline and motorway use; the 2.0 HDi is far better.
