lol , i couldnt care if 20 fridgies say its bla bla bla, i've seen this fixed in practice (usally rich people who think thats there is a problem and want it gone )... if its light mist/fog for a few seconds then yeah thats natural in most aircons , some dont do it at all , fully newelly regased or not - but if it is 'REALLY' visible and almost pure white then this is the core freezing a tad (so long as u can't smell gas ! ) - which is NOT any drama or really a problem ... as i have been trying to state all along it only becomes a problem when the aircon thermo fully screws up - and in some cars it will freeze the core and u will get very reduced air flow too (or none at all in worste cases)- or in the case of cars with the safety valve it will shut down ...
Please guys i dont wanna argue and i wasn't even originally saying this guy had this problem , as i mentioned it was just incase if he got any of these symptoms later , if it stays as is then its fine .... as i said im only quoting what i have seen done with my own eyes in my mates workshop and he described it to me what he was doing , and it got rid of the mist 'so called problem by some' / usually rich picky people ! with bmw's and stuff. Im no fridgie i'll say it again, but i saw what i saw done so i have to stand by it .. ;)
