Re: The Buzzing Bees

[Alexander van Gerbig <avangerb@zoo.uvm.edu>]

Buzzzzz, that's the noise I hear every time i drive around with the stereo on a
low volume.   My 1988 Audi 80 has had a busy bee in the rear of the car for
atleast three years and no service place, nor any Audi dealer has made a ruckus
about the fuel pump dying.  Although I have heard the loud humming noise is a
sign of a sick fuel pump or a fuel filter that has a flipped sock in it??  got
me, (just a shade tree mechanic).  although during the winter months every Audi
in my family has a distinct humming noise, 200 20V Quattro, 5000s(the loudest),
100s, A4 1.8T q.  but i have numerous fuel system problems that have been
fixed, so the buzzing could be causing all these problems, but who nose?
