I pulled the battery to replace it and found an intake hose with an ID of about 1.5 inches disconnected.
What is this hose for and it is possible it was disconnected as part of the emissions Fix or the charge cooler icing problem?

This is a 2014 Jetta Sportwagen TDI DSG. CPO car with an appointment next week for some issues.
Background
For about 6 months the car occassionally will misfire and bog under acceleration. It is random and can happen a couple times a day or go a month without happening. I hit the throttle to go, the car bogs and looses power, and then clears in about 1 second and takes off.
Last Sunday I had what I thought was an iced charged air cooler. The car started fine at 25F. I drove 30-40 minutes to the snow park to ski. I came back 4 hours latter and the car started then immediately died. (Temp 39F) The next crank got about a 1/2 turn. The 3rd attempt nothing. 4th attempt it cranked fast for a about 2 seconds and started but died again. 5th attempt nothing. I jump started the car and it cranked, ran rough for about 30 seconds and then idled normally. I drove to an auto parts store for a battery capacity test and they said the battery was fine. The lights on the dash were fine, not dim, no warning lights. The next morning the car started again at 22F and it has started and ran find all week until..
Last night (5 days later) the car cranked slow coming home from the store but started. Got home and the voltmeter says 12.4V. Put the battery on a charger and it says it charged to 12.8v but the next morning it is down to 11V and the lights on the dash flicker and lots of buzzers. So the battery is dead, I pull it out and find mystery hose.
So could this hose be causing by misfire under acceleration? For my trip to the dealer should I leave it disconnected tell them about it. Or should I connect the hose and drive the car for a bit to see if it fixes the problem? The car is CPO but they charge a $155 diagnostic fee if they can't replicate a problem and don't fix anything.
