I decided that I was polluting Travis' classified listing talking about this so I would just move it over here:

I have a small coolant leak on the 1.8T Schwaggen, I almost drove the ghia today...
But decided to risk the drive to work, looks like one of the hoses from the coolant rail along the top has swollen and is leaking around the clamp... 140K I guess it is time.

The hose that goes to the oil cooler?

Travis - It is a hose that comes off the coolant rail about 2/3rds of way back on driver's side.  It bends under and through the intercooler hoses and appears to dock to the block right where the oil filter screws on.
I have not actually seen it leak, I checked last night when the warning light came on about 3/4 miles from home, all hoses were dry, there was some coolant at the leading edge of the hood on the inside, looks like it was spayed there, but I cannot find out where. no drips and no wet hoses, but this hose appears to have dried up (white residue) coolant on it and looks swollen around the coolant rail side.
It was dark and engine was hot so I could not hear any drips or such with all the heat shrouds popping and creaking from cooling down.
I put some H2O (about an 8oz cup worth) to get the resovoir full again.
None of the hoses felt rotten enough to rear in half, but somewhere I have a leak.

Have ran the car all day and drove and checked it several times, all the tell tell signs are there, crusty spattered hoses, etc just no leak...
Gonna run it by the dealer on Tuesday, or I may just trade it in....
Looked pretty hard at a "new" 2012 Jetta TDI 6sp they have on the lot. It isn't a program car it has just been there since 2012, I think I can get a deal in it.
Was kinda surprised to see it in the back of the lot. The 2014 sitting next to it was only ~1800 more on the sticker for basically the same options.
I am gonna decide over the weekend if I go in and offer them like 18K for it (sticker is 22).
I'll probably just chicken out but it was fun to go car shopping this morning in the rain, the salesmen were too lazy to walk out and bother me for about the first 15 minutes, LOL.

When I lived in Knoxville, I took Bonnie (with a straight stinger) out to the Chevy Dealer because my Dad HAD to have a new Corvette (I think it was in 2008, when the new body style came out). I rolled up load as hell, parked in front of the door and stepped out. They asked if they could help me with something, and I said, "Where are your new Corvettes?" They didn't move..."Over there." The new guy finally came over and talked to me. I explained they my dad wanted to buy one IF they had one with the options he wanted. Dad finally got one down near Atlanta, but I'll never forget the one time I didn't get hassled the moment I stepped out of my car at a car lot!

May be a really slow leak combined with the colder weather

That has been the general consensus at the dealer when we discussed it this morning.

That plastic coolant flanges are bad about leaking,  that would be drivers side,  the water pumps also leak occasionally that's passenger side,  I think all cars now a days are using plastic for everything in the cooling system

Coolant flange on the back of the head were bad about leaking,  real common to see the crusty around the oil cooler above the oil filter

^ This.
Went ahead and replaced the sensor while they had it apart.
~$365.
I didn't want to mess with it.

Russ, I wonder if they would touch your Audi in Dalton...
I wonder if they can look up the parts.

After examining my engine and then looking at pics of the coolant flange in question, I'd say that's where my leak is too. It's dry on top and has some caked on crap around the flange.

It's kinda creamy color but I do run G12.
