Asked this on the Q7 board, but figured it'd get more attention in the TDI Section - I'm doing some 'work' on my 2012 Q7, and need to find the SCR/DEF controller. Can point me in the right direction...

I just replaced the compressor on my 2005 4.2. They are a common enough failure on the S4 of that vintage, that I believe that high RPM usage on higher mileage vehicles kills them. It's possible...
