    Mines like that on my 2.0TDi, sounds like a quiet hover if you stand near it only when stationary, I don't mind it

    Mine goes pretty loud too sometimes. It appears to be the air con fan on the radiator, as I turned my air con off for a few days to see if it was that, and even over the hot weather the fan still did not come on.

    Put the air con back on to say 23c and it makes a huge noise while its working hard again. Not sure if there is a solution, or if its just how they are really, but would be interested to know, incase the bearing is gone or something :)

    usually it can stat getting loud when your air con pressure is running low as the fan goes into turbo to compensate, worth a check on vag com

    Is that when you have to get it Recharged? Or more serious than that?

    Exactly what mine does as well. No idea what it is though, haven't had a chance to look yet! Getting kind of worried now so will get it looked at asap.
