Your car should remember what mode you were driving in for approximately 4 hours after you turn off the car. Any longer than this and then it reverts to comfort mode when you start up. Apparently it's a safety feature so unsuspecting drivers don't hop in when you have it set to race mode with the traction control off and end up wrapping themselves around a pole

Might be a shot in the dark here but on previous M4 we actually wired the valves open so that the car always had that louder cold start up. Is that something we can do here?

Just tested it works in all modes individual / comfort / sport / sport + / race
It's always left in individual though
Only thing that doesn't remain based on the last setting is sport traction if I leave it in individual...but valves are definitely opened all the time unless left in comfort

In the US it is a EPA thing as the car Mfg. cant' count the mileage gain with the start stop if it does not default to comfort.

On the S63 the valve stay shut on Comfort, on Sport at idle it opens very slightly and its opening varies by throttle actuation. I don't understand the point of this design as it creates a lot of wear and tear for the electric motors.
I would be interested to hear any ideas to keep them completely open at all times.

The W222 S63 has the same actuators and am told it will pull power if unplugged. The way they are mounted doesn't allow wiring them open like the BMW cars. If you set the actuator aside and leave valve open the motors spin freely and it throws a code.

I'm almost always in either race or individual mode, and the noise at idle greatly depends on how hard you have your foot on the brakes.
The harder you press, the quieter it gets.

One upside to the domestic simpleton's ... in my Corvette I just pull fuse # 10 from under the passenger side dash fuse box, and it keeps the NPP flaps open at all times. Throw the fuse back in, and the NPP exhaust goes back to its normal operating procedure of opening at 3000rpm.

In the 'Dynamic Select Switch' chapter of the owners manual:
"If the ignition is switched off for less than four hours, the previously selected drive program is activated when the engine is next started. If the ignition is switched off for more than four hours, drive program C is activated when the engine is next started."
