Audi Repair: multitronic trans, drain bolt, dipstick tube

Question
How do you change the oil and flush the trans on a 2004 A4?

Answer
I believe this is done by transmission places through the dipstick tube.  Not sure if there is a drain bolt anymore.  I think they do still have filters though, and you can only get to that by unbolting the oil pan from the transmission.  That could also be a very fast way to change the oil.  Put a kiddie pool underneath the car if you attempt that one though...!   Let me know,  Jan
