The verdict- sucks for me, but it's legit... (longish)
<center><img src="http://pictureposter.audiworld.com/87304/bentlyoilcooler.jpg"></center><p>Previous repair was, in fact, the usual plastic oil cooler pipe between oil cooler and block. They did do the proper repair, including the pipe, all 3 coolant o-rings and the oil seal: items 23, 22,24,(unlabeled one for the rear), and 25 respectively on the attached diagram from Bentley. (lifted from Paul W's page- Thanks!)
When I went in to pick it up, explained the issue with the printouts of ETKA digram as well as a page from Paul W's AudiPages procedure.
The new problem turned out to be the seal between the cooler housing and oil filter mount. The seal is item <b>20</b> in the diagram. He also replaced the two internal o-rings (items <b>18</b>) and I believe the seal at item <b>11</b> just to be safe. The "normal" repair procedure takes the cooler off, and replaces all the seals for the external connections, but not the internal ones, which is why I had to go back in this time.
He did cut me a break on the labor, since they're starting to get really good at it (he had a 2001 in the shop at the same time for the same type of problem), but that's still $510 labor on top of the $640 from the original repair.
I will go on record as <b>HIGHLY RECOMMENDING</b> that anyone who does their oil cooler repair, or has it done at a shop, <b>replace the internal seals while you're at it!</b>
Paul, would you be willing to update the "official" procedure to reflect that? I would hate to have anyone else get stuck for an extra 500 bucks or multiple hours of labor/frustration for want of $20 worth of gaskets/seals that could be done "while you're in there".

When they did mine, everything was replaced.
Even a whole new oil cooler which made me think "maybe" they redesigned something??
Could have been overkill I suppose, but since it is a tedious and time consuming repair, best to do it only once.
I'm glad I opted out of doing it meself because now if it fails again, I can at least bring it back and "hopefully" get some satisfaction for spending 8 large.
Car is perfect now, save for a shreaded tire from S.O. attempted motoring whilst a nail lodged inside:/
So, on tap tomorrow is the winter tire install and new pads all around while I'm at it.
