I was washing my '10 Q5 today and went to open the fuel door to soak up all the water that collects in there (that is an annoyance, there really needs to be a drain hole). The fuel door wouldn't open, I immediately had one of those "oh great, this is a stupid malfunction" moments and was trying to remember how much gas I had left until I realized something else. I had always thought it was a dumb design to have a simple push open fuel door with no release handle inside the car. Then I started thinking like a devious designer that loves everything electronic and realized they must have built in a time lock mechanism. If the car has been off for a period of time the fuel door won't open. I started her up then turned her off and sure enough the fuel door opened on the first push.

Hence a "duh" moment, I still haven't looked in the manual to see if it's documented.
