I have owned our car for two weeks now and absolutely love it. The only concern i have is reading all the bad reviews on the d.p.f system. Most reviews on the web say this is not a car for short journeys and can suffer from expensive problems with the filter. Seeing as most of our driving is short town stuff but do go on good runs at the weekend. Just concerned if we may have problems. Any 2 Litre 143 b.h.p. Diesel owners with any feedback please.
