Yeah I did notice the TSB but thought it only applied to the GT's with the leather, although obviously the suede on the Touring seems to have the same issue. I did mention it once briefly to the dealer awhile back but they didn't seem to think it was out of the ordinary. Doesn't bother me too much, as I've seen leather seats on new Audi's do the same thing, but thought i'd ask just incase others on here had successfully warrantied it.
Thanks
