2001 Audi A6

Engine Cooling problem
2001 Audi A6 6 cyl All Wheel Drive Automatic

I have an 2001 Audi A6 2.7 twin turbo and I need to drain the coolant / antifreeze. However I can't find the drain plug. I read on another site that it's "on the backside of the subframe crossmember, recessed about one inch into the casting of the engine block." I looked for HOURS under the car and can't find ANYTHING that looks like it'd be it. I also read it should be an 8mm allen wrench key. WHERE IS IT?!?!?! Please post a picture if possible. THANKS!!!
