I always drive in S+ mode, since it is loud and it pops and grunts, especially during downshifts and high rpm lift off.
But, it no longer makes that loud double pop when I lift off a high rpm anymore, instead it gives a very muted double pop
What's happening!?
In the other hand, downshifts still makes the loud double pop, which is a relief. I hope this doesn't get muted too................

Ecu controlled valves (3 separate sets) not opening up as much or anymore
Just took mine in for a service last week, it was much quieter and runs much cooler too, my oil temperature used to be stratospheric (104°c) but now it settles at 88° C but it is quieter and i hate that

Those "Pops" are just wasted fuel burning off in the in the down pipe. If there is new software making it quieter it is also probably making more efficient .

Didn't make the slightest difference to fuel consumption which to be honest it's only slightly better than my old 6.2

I wonder if its due to the car having learned throtlle positions etc in the TCU and having softened the settings..
With nothing to lose i'd try a throttle reset (TCU) and see if it returns..
Sucks that this is happening to the perf exhausts...I remember my stock C450 setup also lost volume and intensity on the upshift pops, however, my exhaust has been getting gradually louder 2 months and 1500miles into running the Awe tuning touring setup

That oil temp is off the charts!!! Glad it settled down.
I let a friend of mine drive my car after I broke it in and he mentioned something about the exhaust not having broken in yet. We had another person standing by and watching the hoonage, and he agreed with the exhaust comment. I kind of just shrugged it off not knowing exactly what they were talking about.
Maybe they were on to something? Does the exhaust really get broken in, and you get less of the random fuel popping? The guy who drove my car knows quite a bit about cars, and he even races in his spare time with his own race spec cars. Maybe he was right about the exhaust breaking in.
Googling exhaust break-in, looks like some guys on a BMW forum were talking about their exhausts mellowing out after breaking in, so I think over time all of our performance exhausts will just not be as aggressive.
I just wish it would sound like it does on a cold start all the time.

What is the normal oil operating temp? Mine runs at around 100 degrees, which at first I thought was really hot because the AMG display in the instrument cluster has the mid point for the engine oil at about 85 degrees, and 100 degrees is about 3/4 of the way along the gauge making 100 look pretty hot. But then I bought up the engine info on the Command Screen that shows Power, Torque, and temps. On that display 100 degrees is half way, with cold being down at 70 and hot being up around 130.
So what's normal?

As much as I wish that this isn't the case...it seems to make sense...
my oil would go up to 100 when I hit the highway and drive it for long hours , however it usually starts to cool down once I reach and cruise around the city. its not abnormal for it to hit 100 dude, nothing to worry about. however, it shouldn't exceed and/or stay at 100+ for a long time (that's what I observed from my car)

I am in the US so it is in Fahrenheit but 100c is 212f and my car is about 213f all the time after warm up and always has been. If I really push in canyon driving it goes up some and if I drive easily at 70 it might be a little lower.
Trans is about 183f normally and will go up in 190s with hard driving in lower gears.

My exhaust isn't as loud as before
