How reliable is the Citroen C4 Grand Picasso?

Hi David,

They’re not bad actually. The only major mechanical items that cause regular bother are the engine’s exhaust gas recirculation valve (if the engine is down on power or putting out lots of smoke, suspect this…) and the fragile water pump on the 1.6 HDi diesel. That 1.6 also needs a steady diet of high grade oil at service time. The only other issues are minor electrical niggles, such as the electronic parking brake, sticking fuel filler flaps and the like. Buy one with a full service history and keep it serviced and you should be fine.
