Hi there, I just recently bought myself a 2006 A4 2.0T and so far love it. Just the other day however i noticed i had leaked coolant all over my driveway. I have done some research through this forum and a couple others and I believe the problem is my coolant flange. Now i am not sure if its the seal or whole assembly i will need to replace. Is the flange on the side or back of the motor on the 2.0Ls? I am new to Audi's and am wondering how difficult of a driveway/ personal garage job this would be. I know the part is cheap but I am getting quoted about 4hrs for labour...which sucks. I would like to do this myself but am wondering how difficult of a job this is.

 

Access is a b*tch thats pretty much it. You're looking at 2-2.5 hrs of work.
Check this out. There may be a DIY on this forum as well. It looks like if you take off the PCV assembly, you'll have more room. Also, I believe that there's a recall on the PCV--so you could replace and get reimbursement from AOA. In any case have fun!
