hi everyone,Any user of BMW 1 series user, salesman, technicians here? Plsss to do a favour..mind to check for me whether 1 series got an "insulation layer" something like large pieces of black color wool sticked underneath your front bonnet ? normally its purpose is to reduce engine sound on outside one .. mine brand new 116i doesnt have it.. so not sure bout the rest ...... thanx you sooooooooooooooooooo much!!!!!
