Forget it as I had it from factory on my S4 & it was completely & utterly *****, you'd need aircon on a fair whack to get that to stay cool & remember its only active when the cars in use so you stick a can in there in the summer or choc bar etc it will be nice & warm or melted by time you come back to it, its not worth the time/money.
I thought for one minute it wasnt working so I took it apart & saw it was just a kinda breather pipe of the aircon into the glovebox & realised it wasnt broken, just wasnt very good as everything was attached & working as should without leaks.
Not one I'd recommend, however the 12v coolbox you can use from the boot socket is much better as it constantly uses battery so keeps things properly cool, installing the socket if you dont have is fairly simple & coolbox is an audi accessory anyway, I'd recommend this more given it works anytime not only reliant on another system running.
NICE.
