Reliability, common problems and owner reviews for the Peugeot 508 2.0 HDi / BlueHDi (DW10). Check this before you buy used.
The 2.0 HDi and later 2.0 BlueHDi (DW10, the long-running PSA 2-litre shared with the 407, 308, C5 and Ford Mondeo) is the 508 engine to buy — strong, refined and ideally matched to the large saloon/estate. Standard modern-diesel items: DPF (with the FAP cerine-additive system on HDi), EGR, injector wear, the timing belt (this is a belt engine — do it on schedule), and AdBlue/SCR on the BlueHDi cars. Maintained on time it's a genuine 300k long-hauler; buy on belt, DPF and injector history.
