Compressor Sound when Opening Driver's Door

Does anyone else get a compressor type noise when opening the front door to their Audi?

I am not sure what it is. It sounds like either the heating and cooling system or like something is being primed before I turn on the engine.

Um yeah that noise when you give contact to the car, is your adjustable headlights that turn on also there is a pump that preps the system for start up It is very good to turn the key and let it sit for 5 seconds before starting

happens with all cars - my wifes' jetta does it when you unlock with the key fob, my WRX does it when i half-turn the key

methinks it's the fuel pump.
