See, I find mine quiet loud when it's idling. Obviously much quieter than my 320d. I had a bit of a read around and it's a negative mentioned in a few places.
Also, do you enjoy the power more in normal or sport modes? I think I'm a bit weird as I love the turbo kick in normal!
I've not found mine too bad. Maybe I'm just too used to diesel engines, or I'm deaf. But even people I've had in the car have remarked how quiet it seems.
And so far most my driving has been in normal or eco pro, but once things are worn in a bit more I'll probably thrash it more in sport and let you know
