High pitched whine
 

Quick one:
When I start up my 2003 A4 Avant 1.8T, a very high pitched whine is emitted from somewhereunder the rear seat. It does not matter if I am in drive or park, as soon as the engine starts, the sounds starts with it. It sounds like a mosquitoe buzzing beside your ear...it is that high pitched and quiet. Barely audible in fact, but it is definietely a new sound. I can here it better outside the car, rather than inside the car. It is not stereo related. I think it might be the fuel pump. Any thoughts?

Also I have a CD error 3 that just came on the stereo (completely unrelated). Is this covered under warranty?

Have you had the recall perfomred on your vehicle. 03's are supposed to have the fuel pump replaced.

Fuelfilter is mos def the problem. I had that problem a month back and i had it changed ASAP. I went to the dealer and bough the filter for $47.00 and changed itr myself.

Since i have changed it i have not heard no buzzing or whinning from the back

You may want to change this ASAP becuase if willcause trouble to your fulepump.
