What color is the coolant in the reservoir?
Probably a bad coolant flange.

or simply the o-ring surrounding the temperature sensor..

mike i dont see any coolant in the reservoir and the reservoir is discolered planning on buying a whole new 1 but need to find where this leak is coming from like badly so i can get it running, thanks for your help both you ima check and see if those are any of the probs and will get back to you and let you know again thanks for your help

Green= power steering fluid or air conditioning PAG oil if it is fluorescent green.

i have a feeling the previous owner put PEAK or some other green coolant in it
flush whatever might remain of your coolant and fill with the right G12 mixture first before you go buying parts
here's a DIY if you need help with that: http://www.audizine.com/forum/showth...h-Your-Coolant.

as far as your leak, what is your car? 1.8T, 2.8?

coolant res. is empty suspecting some kind of leak there.
also its a 1.8t...
and the fluid is fluorescent green
also alot of the hoses look like they been rotting from the inside...

florescent green, almost yellowish, im going to say a/c fluid, freon..

Just use distilled water in the reservoir to help diagnose. Chances are, if the reservoir is empty, and you didn't know what was in there before, then it probably is the green stuff.

I personally run G5.

alright soor y to get back so late.. so i did the coolant flush and theres no leaks there, so ima assume its the a/c but how would i find the leak there??

You would take it to a place for A/C service and pay them cash dollars to fix it...basically. They have special tools to pinpoint refrigerant leaks, and more special tools to properly evacuate the system, repair it, and refill it.

If you want to save money and do the part-changing yourself, you can take it there, have them find the leak and evacuate the refrigerant. Then take the car home and change out the leaky part yourself (probably the condenser or compressor). Return to the shop for a refrigerant refill.

I'm kind of wondering how you are leaking refrigerant oil near the axle, though. That's kind of odd. The common leaks are at the condenser (from rock damage, etc), compressor itself, or various line fittings/o-rings. There's not any A/C stuff that runs very near to the axles or transmission.
