    Hi,

    Is it normal to hear noise like a motor running when i open my drivers door for about 3 seconds? Seems to only do it if the car has been sat for a good few hours.

    i've heard that - sounds like a hiss - as though compressed air is being released for a few seconds...couldn't work out what it was!

    Think it's just the fuel pump primming itself. Quite normal.

    That's what I thought too - only happens with the drivers door too I think. Happened on all the 3.2s I have driven.

    I get a buzzing noise when I switch off the ignition and open and get out of the driver's door after a journey. Only lasts about 5 seconds - presumably this is normal too? Always done it. Seems to come from the engine bay.

    I flagged this up with an Audi technician and he said its to do with the emissions system and perfectly normal - never heard it on my 140, but I hear it everytime on the 170 and it lasts about 15 seconds.

    It is the fuel pump pressurising the system...

    Does this refer to the hissing noise Edition gets when opening the door from cold or the buzzing I get when opening the door to get out after a journey?

    Cheers!
