Pink(G12) coolant in the overflow tank, but it's leaking clear or light green fluid?
Do you have a photo of the area it's leaking from by any chance?
Does the color of the fluid leaking match the color of the fluid in the washer fluid reservoir, Or the power steering fluid reservoir?
The OEM power steering fluid is light green and the metal cooler lines for the power steering are located right in front of the radiator (well I'm referencing off of my 2.8, I assume that much is the same throughout the platform).
Regular washer fluid is blue in color and sometimes the headlight washers that are located to the left and right of the radiator can leak.
Make sure it's definitely the radiator that's leaking.

Crawling under it this morning with a flash light allowed me to find the source of a leak, the bottom trans fluid connection at the radiator, looks like white fluid is seeping from there. What color should the trans fluid be?
The power steering fluid is green and looked like what was leaking but I didnt see anywhere that was leaking from at the power steering cooler. So I may have multiple leaks then...i need some ramps to get up under everything better because jack stands are a pain in my littke one car garage

As far as "white" fluid.. I'm not really sure what that would be. Is it old dried fluid from the leak maybe?
BTW is your car Quattro or FWD? It's not really related to the issues, just something I'm wanting to know.

Its an awd
The leak has dripped clearish brown, clear, and goldish green. I think your right about it drying into a clearish white, and it has been drying gold brown color on driveway. I will get pics up tonight

I just looked briefly this morning before work and it was pretty full, I have no idea about it being flushed or filled, the po really couldnt tell me anything about the vehicles past as he said he had it for only 6 months, but the fluid in the ps tank looked alot like what was dripping. But maybe it is just the trans fluid..or maybe I have 2 leaks, we shall see

States in a post there is a newer atf that is green. now when I looked at the leak this morning there was the white/clear fluid between plastic and metal fitting. could it be a leak at the o ring, or could it be an issue with the rad itself?

it is coolant that is leaking...it appears to be clear on a light background and light green on a dark background such as the black radiator...I looked over it more today after work and found it is leaking from the lower metal atf connection: BUT it is leaking from between the plastic and the metal. It looks like the trans fluid is not leaking at all. I am thinking that the po did mix some green coolant in and that is why I have seen green, clear and brownish fluid that leaked...now I need to find out if that metal outlet turns and tightens to an internal cooling line in the radiator...I don't see how it couldn't. it has to mate up some how and has to keep the coolant out of contact with the trans fluid.
I know that it is coolant because I can gently push up that lower trans line and some fluid will drip out...now all of today it has been completely clear when on my hand, but when I look up at the leak with a flashlight it is light green...I then decided to crack the drain **** on the radiator hose and coolant sprayed out...same exact fluid. this Saturday I should be able to get that lower trans line off and see if I can tighten the outlet and fix the leak then continue with a full coolant flush and g12 fill up. If I cant fix the leak then I will flush it with old radiator and order new, install and add g12. Either way I think I am on the right track. I think I am going to go ahead and order a new coolant overflow tank as I see a couple fractures in it and may as well replace that when adding the new fluid so I dont have to worry about it later. thanks all
pic shows the outlet: coolant is coming from between the plastic and metal piece. The outlet should spin to tighten on to internal piping correct?

Update: did the coolant system flush.
http://www.audizine.com/forum/showth...-(the-easy-way)
After dumping the coolant on the 2nd or 3rd revolution, I disconnected the lower trans fluid line. The metal connection was able to turn counter clockwise to loosen and clockwise to tighten. I was able to turn it another 1/3 of a turn. Got the trans line back on and kept flushing the coolant system another couple times.
After the coolant looked clear, I took off the old coolant expansion tank, and hooked up the new that came in the mail yesterday. I then added the pentosin pentofrost sf I bought earlier this week to the expansion tank. Had to empty one bottle, then drive around for a couple minutes to circulate it. Let the car cool down a bit, then popped the reservoir cap and added the second one. After driving around after the second one, I am showing a bit low on coolant so will add some distilled water, as the 3.0 holds 6 liters of coolant/water and is a 50/50 mix.
After 30 miles I am happy to report that my leak is fixed and my coolant looks as it should. Now, on to the next issue. I am leaking a red fluid from the gear box after the transmission. Its hitting the exhaust and smelling pretty bad. So am assuming this one is some type of seal...Any advice?
