I just pickup my TT 225 Roadster Amulet Red with Aviator Gray leather.Anyway Iam also hearing a sound @ 2500-3000 rpms and @ 4000 does anyone have any ideas???The service rep as no clue said he will call the factory rep.Also anyone else with a seat that vibrates over bumps.

Same things with the passenger seat vibrating a lot. Especially the head rest. The problem with the sound betweeb 2500-3000 rpm is a Diverter Valve:
