For those who have had their dash apart...

[billschroeder5842]

I'm indulging my OCD and chasing down every minute squeak, vibration, click, tick and buzz in the car. Through hours of taking things apart, adding foam, zip ties and tightening everything I can get a wrench on, my car (for a C4) is remarkably quiet.

Except....

I have a slight "wobble" noise coming from somewhere in the dash that only seems to appear when I go over a "washboard" type uneven road. I'm having difficulty locating left, right or center in the dash. I've had the dash apart looking for this little guy, but never pulled the actual dash pad. I've read the TSB on noises and followed them all down. I'm stuck on this one and although admittedly crazy, I'm hesitant enough to not pull the dash pad-- yet.

For those who had had the pad off, is there anything "going on underneath" that may be making the wobble noises that is pretty common/obvious enough to reconsider pulling the pad?
