Squeaky suspension ???
 

My '01 A4 1.8T squeaks whenever it rides over bumps and I notice it when I push down on the car. Notice it more that the windows are open. Any thoughts ???

This sounds like another control arm problem

Same Problem here, getting it looked at the 22nd, will let u know what they say

I had that problem as well.
 

I had my control arms replaced a month ago. I have a 99.5 with 25k on it and had the work done a month ago, and guess what?? The sound is back!! With the window open, when I hit a bump I get a squeak or screech sound. I have complained about this several times and they lubed the suspension and retighted it. The last time at the 25K service is when they replaced the control arms completely. Didn't seem to work as the sound is back. This is starting to drive me nuts!! How can Audi not be able to fix these problems??
