02 audi a6 Quattro coolant leak
 

This past weekend my car developed a serious coolant leak. The coolant is coming from the back side of the engine block on the passenger side. I have done some research and know there is a aux water pump back there and was wondering if that is a common fail point on 2.7t engine or does my car have a bigger issue.

There have been many threads on this on the C5 forum. Do a search there and you will find answers.
