Ok, so when all fans are off, its as quiet as my very quiet MY LR, when I turn any heat on, DB meter has same or actually quieter sound output from my new MYP but to my ears I hear a little bit of that noise that we have in our cars with noise where in my original MY LR the pump sound doesn't exist ever running air conditioning/heat no matter what, but again with this MYP the pump sound is there with heat on, but not as much for sure..... I haven't driven it much yet but will report back. My wife immediately told me as well, this is a much quieter car. I am finally happy, overall... there were small issues with car but i can live with it.... (rear lights are sticking out more then any of the cars i've seen before, im thinking of reseating them myself.)
