Engine noise
Curious - how loud is your 450 when at idle on a cold start? Ours seems to forming the “diesel” noises. Not unfamiliar with MB here, I know their engines aren’t exactly quiet like a Toyota, but this seems a little excessive to me, does it to you? What does yours sound like? Do you have that rhythmic tick as well (not the injector noise, the other noise). I know the direct injection noises well, but this one has another in the background that is a little slower noise. Car is at 31k on the clock.

I picked up mine yesterday and it sounds exactly like that.
I had other issues
1.) 3rd row Left side seat does not fold
2.) Power Sun Blinds do not come up although the blind holders do come up. Looks like Blind is not attached to holder.
3.) Turning the fan up or down for rear second or third row also turns the front row fan up and down. not sure why.

Thing to note is the dynamic mode you are keeping it on may change the sound. I keep on Comfort mode. I will tomorrow record one in comfort mode, another in sports and third in sports+. The sound will vary because in comfort mode RPM shows really low around 500 while in sports+ I think it is around 1500 at ideal state.
