Hi, I've just noticed that my 2 1/2 year old doblo has developed a low rev turbo whistle, is this anything to worry about, its only done 41k, should I get shut of it ?

Not really anything to worry about? Although correct me if I'm wrong... every 1.9JTD I've test driven, and mine now all produced a turbo whistle at low (1900+) and higher revs

It's quite nice actually
