Hissing sound from under the rear part of car
Hi all,
I have an A4 1.8T, 2002, with 70K miles. Recently I noticed that high pitched hissing sound that comes from the rear part of the car. I pinpoint the car from somewhere in between the two rear wheels.
The noise is not there all the times. Usually when the car is idle it disappears, but then re-appears when press on the gas.
Any ideas what the problem might be?
thanks in advance,
nick

I thought it could be a fuel filter too but if the noise is gone during idle...
and comes back during acceleration, it makes me think it could be something else.
I thought the humming was just constant, idle or no idle. At least on mine it was.
