So the last time I went to a tail gate I had my windows down the trunk open and I was listening the radio. Car was off.

After about 10 minutes the radio turned off.

If i pulled the key fob out and put it back in the radio would start back up in auxillary mode and play forn another 10 minutes.


Is there a trick to keep the radio on or is this Audi's way of preventing a dead battery?
