I will bet that you do not even KNOW what the conditions are which might cause the sight glass to indicate ( by still having bubbles ) more refrigerant was needed ( when it is actually full ).
Come on !!! it is an open book test and I will bet you can not even find and tell us what they are.....
If you did know them...( very unlikely.... given your defense of ' I have been doing it this way for x number of years and it worked for me ' ) how simple and KIND it would have been to list them when you said that...
" I have been lucky over the years not to have had any problems overcharging AC systems using the sight glass method... even though this method is warned against in the MB AC Factory Shop manual ..
BUT is it possible under A plus J plus X conditions to get a false reading and you wind up with too much refrigerant in your system " ...
SO EASY !!! SO SMART AND KIND to others who might not have the background to understand that you are depending on luck instead of what the makers of your car go to the trouble of researching and printing in the instruction manual....
