Guys,
The process of combustion produces water and carbon dioxide whether it is a candle on the table or a rocket engine launching a space craft as well as those IC engines we love. Catalytic converters and all those other post processing of exhaust gases are to deal with the small fractions of the mix that didn't complete the reaction in the combustion chamber. The unburned hydrocarbons that are "converted" (combusted) form a little more water and CO2. In very general terms - sort of a hip pocket estimate - a gallon of fuel will produce about a gallon of liquid water. The heat of combustion usually keeps the water in the vapor state except in very cold environments where dripping tailpipes are common. This is the first I have ever heard of an exhaust system freezing up and I live in northern NY. I have seen weep holes in mufflers before but I do not know about my 2010 TDI.
