I have a friend with a 3 year old Audi A6 (2.7 diesel I think) that has
had a problem for a long time now with the aircon intermitantly going a

Garage is at a loss as nothing shows up in the computer logs (and I
guess intellegent guesswork/diagnosis is beyond them) and because the
problem is only intermittant and typically never happens when it's taken
to the dealer.

Are there any common known problems with this car's aircon?

TIA

If it's random then you'll want to plug it into Vag-com & see what's going
on, normally it's a sticky flap or motor but interrogating it's a lot
easier than removing the dash.
