Well, I have found the limitations of my drain. Assuming, rather poorly, that the moisture was being ingested while driving during high humidity and inclement weather then condensing and collecting in the piping, my system would work great. But, as in the case today as I am headed out to get the kids from school and the car won't start, the valve located above the drain won't do me any good. I had just purged the system on my way home from the school run this am. The car sat in the garage for 6 hrs and in that time, gathered enough water to cause a no-start issue. Thankfully I have a backup vehicle! I am guessing there is just shy of 1 cup of water here:
The weather has been sunny, but the high was in the low 30's, which is about 25* less than yesterday.
So, I need to think about how I can drain the water when the car isn't running. Not sure my tubing is large enough for a gravity drain. Maybe I can route my existing tubing and valve to a location that is below the intercooler piping and see if it will gravity drain.
Meanwhile, I have a call into my dealership to see what is being done. I'm getting rather close to throwing in the towel on these TDI's! The bandaid fix isn't doing us any favors.
