Default Coolant Leak, Help!

I went to start my car today (A4 B6 1.8T Quattro) and Low coolant alarm/flashing screen deal comes on, I step out take a look under the car, sure enough drips coming down off the car into a big pool of dried coolant. I pop the hood to see almost no coolant left in my reservoir, I try and pin point the problem and I find this..

Underneath..

Zoomed out to show where I am looking..

Zoomed in on coolant drip area..

Maneuvered camera around inside to get a good look at the drip area..

Seems to me that it is leaking from the area circled in blue, But I do not know what this is.. what could be leaking coolant behind the head there?

Doubt I can fix this today, hope it's nothing major but rather than drive it anywhere and risk any damage i'm just letting it sit for now till I can pinpoint the problem!

yeah thats the coolant flange and its a pain to change you got to remove all that staff in front of firewall so you can have room to work. if you know whats your doing it should not take you that long.

Just did the job 3 days ago on my 1.8T Quattro... my coolant flange was on the rear next to the firewall. here is a DIY writeup that helped me out:

B6 A4: DIY Rear Coolant Flange

Things that helped out:

1. remove the airbox completely
2. use a small amount of gasket maker to hold the large o-ring in place
3. Be EXTREMLY careful with the 2 bolts that hold the coolant flange to the head. I stripped one of the bolts which then lead me to tap the hole and use a larger bolt
