Re[2]: Fuel filters..BUZZ

        That is your fuel pump pre-pressurizing the system.  It is normal, 
     and I like hearing it to know it is working.  However, if it get 
     progressively louder, it may indicate an immenint failure.

    I'm not sure if this is common among all sciroccos, but whenever I
turn the key on my car I hear a loud buzzing sound coming from the 
area where this accumulator would be. Does anyone else have this 
happen to them? I was wondering if there was a way to dampen the 
sound. Some times you can barely hear anything, then there are times 
when it is so loud I can hear it over my stereo, as long as I don't 
crank the stereo.
