    Tried a search on this issue but no joy.

    Just got a 55 reg A4 B7 2.0 TDI S-line saloon and need a bit of info.

    When the air con is switched OFF there is a random/irregular mechanical rattle from the engine bay. However, when the air con/climate control is ON there is no rattle.

    Any suggestions as to the cause?

    If you do a search I'm pretty sure this has been covered before.
