Audi A6 owners have reported 1 problem related to engine head gasket leaking (under the engine and engine cooling category). The most recently reported issues are listed below. Also please check out the statistics and reliability analysis of Audi A6 based on all problems reported for the A6.
Lower and upper gaskets are leaking. These leaks drop on hot parts of the engine and create smoke fume. I had the lower gasket replaced for about $500. I know that similar services are done 2 more times in the history of this car for the exact problem. I doubt that there is a design issue on this area.
