Folks,

Been meaning to ask this for a while now. When I start our A170CDi as well as the usual diesel clatter there's a very high pitched whine coming from the NSF of the car... sounds like a gas turbine actually (I wish!) and it seems to be putting out its own fumes.... any thoughts what this could be?

Thanks!

Rez

Hi
Put up a picture of the area the fumes are coming from.
