My 2006 A6 with cd changer will start just fine after 14 days storage in lower temp. then 5 celsius...

 

Well it seems to have been as simple as changing the coming home settings to shorter periods and I think the most important thing is not keeping the doors open while cleaning the inside. I beleive I was having the doors open for maybe as long as an hour and that was keeping my headlights on as well. I have not had any issues in over two weeks now.

My 2005 A6 quattro with MMI is lighting up randomly on it's own draining the battery. Car sat at the mechanics and they saw it light up like it was possessed when it was just sitting there. Anybody know the root cause? They are checking through every module.
