Sorry for the poor quality picture (mobile phone and poor light conditions), but here's a quick snap of the soundproofing under the bonnet of my E92 335d. It feels like a fairly thin piece of stuff, but I suppose it must do something, otherwise BMW wouldn't have put it there. It's held in place with a few large-headed bolts and seems to be tucked into the metalwork in a few places.
