2016 · Peugeot 208 · 1.2 PureTech 110 · 112,000 km
Root cause: The timing belt that runs in the oil had degraded; belt particles blocked the oil pickup strainer and the brake vacuum pump oil feed.
2009 · Peugeot 308 · 1.6 HDi 110 (9HZ) · 165,000 km
Root cause: Turbo bearings failed from oil starvation: carbon from a leaking injector washer got into the oil and blocked the turbo oil feed filter and the sump strainer.
