Alright, here's one for you guys. As my title reads, I just purchased a 2015 Touareg Sport. A mysterious subtle, light rattling sound is coming from the passenger side. But you can only hear it in the interior. And only when the vehicle is idling. When you step on the gas, it disappears. So I took it back to the dealer, and had the service manager get in the vehicle and listen. He heard it also. So I just received a phone call from him. He says that they have pin pointed it to be the mechanism inside the fuel regulator. He says that they also hear this noise inside one of their stock 2015 Touaregs. He says I can pick up my vehicle, and in the meantime, they are going to figure out how to dampen this noise on their stock vehicle. Then, I'm supposed to bring my vehicle back, and they will do the same on mine. Has anyone else heard this noise on their brand new 2015 Touareg Sport? Like I said, it's very subtle.
