hi all, wondering if someone could tell me if this is normal on a audi a3 2.0tdi 2004,
when i have the climate control on, really low setting i hear a humming noise when the car is idle, if a rev it a little it goes away,
just wondering if this is normal, maybe the noise is still there if the setting is on full but you cant hear it i guess with the all that air its pushing out,
the heat/cold air everything seems ok,
whats your thoughts?
