Q7 Dead Battery - 11 days old

Similar problem here. I own an earlier model 2007 Q7 (purchased new nov. 2006). We had left the Q7 in the dealer for minor service with the valet key. When we picked it up, my wife drove it to work and forgot about the valet key since we always use the smart key fob. So, she actually left the valet key in the ignition all day long while she went to work in her shop. The engine was off and the ignition switch was in the off position. Since she's used to the radio and all electronics, lights, etc. shutting off on a delay, especially with the smart key, she didn't think anything of it when she left the car for the day. She locked the car and walked away. Anyway, with the valet key still in the ignition, the radio remained on all day until the battery was drained. We had to jump start it in the evening.
I took it into the dealer and had them look at it. I was under the assumption that the Q7 has a smart computer which is supposed to shutdown all non-essential equipment if there's a chance that the battery is being drawn down too far. They said that it was normal and also showed me the same on a 2008 Q7. I had a copy of a TSB that mentioned something to the fact that it wasn't normal and was fixed by a software upgrade. They still denied anything was wrong and also stated that my software versions were all up-to-date and didn'tneed an upgrade.
He even tried explaining that Audi designed it that way so you could sit in your car and listen to the radio without turning the engine on. Their explanation didn't really make any sense at all. I may not know much about the electronics, but it seems odd that any manufacturer would leave stuff "on" with the ignition switch in the off position, regardless if the key was in the ignition or not. Usually, ignition switches have an "off", "on", and "accessory on" position. If I wanted to sit in the car and listen to the radio without the engine on, then I'd turn it to the "accessory on" position -- not the "off" position.

I heard of a similar problem. Turned out it was a motor sensor in the auto tailgate not switching motor off.

.I have a 2007 Q7 and the battery is dead, I tried to jump it a few times with no result. I am considering charging the battery.How do you charge a battery when its dead, do you have to remove the battery or can you charge it from the port under the bonnet

you can take it off the car(under passenger seat) or charge it via points under the bonnet(better this way) as the battery management will know the battery is getting charged,if you charge it out the car and put it back in the car,the batt managment will still think its a dead battery,unless what you can do is change 1 digit in codeing if you have vcds,this will make the car think new battery is installed.
