Mine did this recently. I blame the crappy replacement cabin air filter. It has a foam edge.

Default Mice?.....>

Don't laugh. Before I changed insulation materials in teh TTDA I had several pics sent me of "Faulty" insulation....:-). The mice loved running up the feed tubes and munching down on that stuff...

Default Thx Steve, possible, but improbable... the foam itself the comes out of the vent is powdery>>

so due to this I suspect our hot climate has taken its toll on the internal foam. Most frustrating after you give the interior a good cleaning to have bits flyig out of the vents!

The hoodliner has also started sagging in places, again due to the heat I think... part number anyone? hmmm, maybe I SHOULD look at a new TT.,...

Default Yup...could be your climate then...But..>

I wouldn't discount critter infestation. I know a lot of the foam used is dense Closed cell type. Scratching, munching, would result in small pieces/dust. I kinda doubt it would deteriorate on its own...Doesn't this stuff live in landfills for hundreds of years??....:-)

Default hmmm, you could well be right - will take some pics tonight of some sample bits

and post 'em up tomorrow for review...

BTW, have been so busy at work I haven't een on the forum for months, but I finally did get around to installing the suspension setup you recommended: along with all of the rubbers, shock mounts and bushings, my Bilsteins have absolutely transformed the car! Thanks for the great guidance, I'm _REALLY_ happy with the results.
