Interesting....
My air con has whined for all of the 8 years I have had it. TBH I thought it was an engine noise until turning off the air con silenced the whine.

Like many have said it is best to use a/c all the time, which I do, but this thread does make me wonder about the new hose fix.

I would love to understand the oil in the a/c compressor, where and if it circulates and how people ruin their compressor by getting oil amounts wrong.

I suppose the ultimate question for this thread is do Volvo dealers have the a/c expertise to advise a customer about this issue and do any fix.

Any thoughts Clan, if I may be so bold ?

This issue is one that I will definately not be doing anything about until I understand it better, as the a/c works beautifully, despite the low engine rev whine since new.
