My diesel sounds more harmonious.
Having said that, since it is a 2012, I WOULD pay close attention to how it sounds for the first 10 seconds of a cold start.
As long as any "clatter" it makes in the first couple of seconds immediately subsides and settles into JUST the agricultural sound of this motor, I'd worry no more.
But if you Do have that nasty clatter, and it IS nasty sounding, and it lasts for more than just a very very few seconds, get that addressed.
If it were not for that one rare but SERIOUS issue, we would still be claiming the Super Tenere as indestructible.
But alas, there is one Achilles Heal in this amazing machine.
