I have a squeaky bird chirp sound coming from the right side of the engine. It normally makes this sound when I'm cruising at 2200- 2700 rpm. I can make the sound fluctuate with the throttle. It also makes the sound when I let off the throttle and its fully closed. It doesnt do the sound when I am idle or stopped. But as I step on the accelerator once it starts passing 20 mph it starts.....squeak.....squeak.....as i tend to go alittle faster the squeaking sound isnt so spaced out...it becomes continuous..

.squeak.....squeak.....squeak.....squeak.....squea k..squeak.squeak.squeak.....
Squeeeeeeeeeeeeeeeeeeeaaaaaaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaakkkkkkk
Then once i start slowing down in tends to space out again. Once I am under 15 mph it doesnt do it anymore........

Please help its annoying and its driving me nuts....and of course I am scared of something going wrong with my B6 =[ (I can try and record a video if someone needs me toooo)

 

maybe check your brakes... mine does the same thing every now and then but it stops once i lightly touch the brake pedal. or wheel bearing. I owned a honda before and it made the same sound until i had the bearing replaced.

if you jack up the car and hold the wheel in the 12 clock and 6 clock position and try push pull the wheel, if it moves then its most likely wheel bearing. dont pull push too hard as it doesnt take much to notice it.

 

I have the exact same problem with my B6 A4 Quattro 1.8T. Normally it's at lower rpms and sometimes on the highway on hills. I've adapted my driving to adjust the accelerator in order to make it stop or at least lessen.
