Yeah I suppose it is quiet. Initially I was very impressed with how quiet the D5 was once warmed up. But in comparison with the 185bhp engine, its noisy that was what i meant earlier. Theres still that clunking sound staionary but the main worry was on the motorways ... on there, you cant tell its a diesel suffice to say, I'm not embaressed having a diesel car because the noise isnt that bad compared to as people have mentioned older cars or even current other makes that really do sound bad.
