HI @MY-Y and @gundarx , i like to know is anything like PE Foam will stick and able to tear-off ? i picked up my car on Mar and im afraid this will void the warranty. My wife and i can hear that noise on driver seats and willing to fix it since tesla service center unable to fix it at this moment.
While possible to remove the PE foam, it will be messy, similar to removing any foam tape which may easily shred the foam while leaving the adhesive backing on the surface. With enough effort and Goo Gone, it should come off completely. The butyl tape once cured may be very difficult to remove and consider that to be permanent.
With that said, the surfaces we’re treating with butyl and PE foam are all hidden inside panels and it would be surprising if anyone inspecting the car in case you trade or sell it would ever see it. For warranty to be an issue, Tesla would have to prove that the sound insulation broke a component or caused its failure. I can’t think of where that would be a concern except maybe by sealing the amplifier so well that it overheats? It’s more like having window tint which would be a non-issue for warranty unless it causes glass failure.
