I have a growling noise when my aircon ( climate control version ) is running .
It seems to come from under the dash , but that may be my hearing , and sort of varies with engine speed , but not conclusively
It is not present when I am just running the demist function . With the bonnet open , the noise does not appear to be coming from the compressor .
I am due for a regas , so I will get that done shortly and see if it helps , but I wondered if anyone else had had such a noise and had any ideas ? Is there anything under the dash which might growl on aircon setting but not on Econ setting ?
The aircon generally works well .
