Frequently asked questions
Which Peugeot 508 engine is the most reliable?
1.6 HDi (DV6C) — Maint. Sensitive verdict. The 1.6 HDi/e-HDi (DV6, shared across the 308, 3008, C4, Berlingo, Ford Focus and Volvo) is the economy diesel — frugal and a bit modest in the large 508, but proven. The DV6 cautions are well known: turbo oil-feed pipe coking (the classic DV6 turbo-killer if oil/intervals slip), DPF and EGR on short trips, and the eHDi stop-start cars adding their own gear. With scrupulous oil and the turbo oil-feed kept clear it's dependable; the 2.0 is the better-matched engine for the body.
