Air compressor sound when unlocking car
Does anyone else hear a noise like air is being released when you unlock the car?
This seems to only happen when the car has been parked for awhile. I know that it always happens when i unlock the car in the morning. Sounds like it's coming from the rear wheel area...sounds like the noise an air suspension makes. Any clue what it is?

My guess, and it's only a guess: That's the fuel tank emission control system doing its thing.
