Help with vibration noise

[drgek]

I have an '11 V10 Spyder with about 3600 miles on it. Over the past month or so, it developed a metallic vibration noise, intermittent in nature, behind my left ear as I drive. It gradually became louder and more frequent. I've tried to pinpoint it to certain conditions, such as acceleration/deceleration, rpm range, but to no avail.

I brought the car to my Audi dealer who also heard the noise. They had no luck pinpointing the source, and contacted Audi who claims it is due to the fuel filter (? retention clip; I really don't have a clue) and the filter was replaced. No change. If due to a faulty fuel filter design, I would have thought that either changing the filter would help, or that the problem would have been there from the start.

Anybody else have this problem, or better yet, a diagnosis or solution? Thanks.

Tap the little pieces of black plastic at rear of side glass. The pieces that don't seem aerodynamic. Mine seems a little loose (right side), so I might add a temporary piece of tape to see if this eliminates my small rattle at speed.

Will try, thanks.

Don't think those pieces exist on a Spyder

My bad!! Sorry!!

An update:

My dealer, along with the Audi field rep, was able to establish that the noise was coming from a resonance being established between the fuel filter and its uninsulated mount at higher rpm. They insulated the mount (not sure what was used) and the problem is now solved.

which mount? the fuel filter to the frame or an engine mount?

Whichever mount holds the fuel filter in place. Don't know what it's attached to. Will ask.
