The one I tested did it and so does mine. I think it is more to do with the turbo, once it kicks in all is quite. I do not know if it has an electronic bypass on the wastegate, but it is noticeable as the car is so dam quite.
I think that's the problem, it's very quiet, almost too quiet. It's a strange sound that still doesn't really bug me (but mildly annoys me). Driving with windows up, radio off still sounds like an old manifold exhaust leak or one of those very old VW Combi's in the distant background.
Then, with door open, in park, rev the engine it sounds like a normal diesel with no sound of escaping air. Also again with door open, foot on brake, in drive, rev engine again it sounds normal.
It's only ever sounds like a manifold exhaust leak from within the cab with windows up. I'm beginning to think it's just a muffled tinny variation to the "diesel" sound. Could also just be my imagination and I may just get used to it. I'll bring it up with the techo's at the first service.
