I have 1,8T and have problem with clima system. Usually it works fine, but in longer jornejs after nonstop driving ~1h or a bit longer, working in Auto mode it cuts off, it cuts off not only cold air but air at all. I switch to Econ for 5-10 minits and it goes back to normal. It seams somekind overheating security? Sallon air filter is changed frequently and it is ok, system is mainteined ones at year so all components have no wisible foults. I even tested it with VAG diagnostic system but it shows no problems. Of course I can not test it in foult moment. Also I found that system generates very much condensate, it seems more than it should be...
So probably someone are familliar with such problem?
I live and drive in Latvia so it is not the hottest spot
