A4 Gargle - Techs read this

["Greg" <mis@postoffice.worldnet.att.net>]

 Here's the anomaly that's driving me almost crazy.

I shut my A4 off after running it for at least 15 minutes. Then, I'll wait
about 30 min (maybe a little less). I'll then start it back up and within
about 1-2 seconds, I hear this gargling sound coming from the right rear of
the car. It only last about 5-10 seconds. To hear it well, you must have
the radio off and the climate control fan turned down.



Here's the probable cause:

I spoke with Shumburg AUDI today in Chicago. Here is what they think it is.


On the Quattro version of the A4, the gas tank is not flat. It is shaped
and mounted in the A4 like an upside down U. This allows room for the drive
shaft to meet the rear differential. The fuel pump is only on one side of
the tank. So, how does the fuel get from one side of the tank to the side
that has the fuel pump?  According to Shumburg Audi, there is an injector
that picks up the fuel and sends it over to the other side of the tank
(where the fuel pump is).

They stated that the injector (not to be confused with a pump according to
Shumburg) is probably making this sound and if the car starts and runs
fine, do not worry about it.

Any comments are welcome as Shumburg could not really explain why it would
make this sound.

I spoke with a guy named Craig in Shumburg's service department.  Seemed
very knowledgeable.  If any of you know him, tell him thanks again.
