Can confirm the extra blurbles and gurgles when pressing DSC once and using the car in +/- mode only. When using in auto I did not hear the freebies. Still a cool thing, but hard to tell if there is any extra overall volume at speed.

completely misread your post lol. I thought you were asking if you could change the modes while driving or if you have to be stationary and at neutral

Sorry I don't understand. I've just got my M2.

So when you say after starting the car, you mean just that right and this Easter egg can't be axtivated once warm?
I pressed traction button once when warm and got the loft off burbles but it also said traction was limited!

So is your method preserving full traction somehow or also reducing it down?

Can someone explain to me what this mode is is this MDM?

To add to this, MDM/DSC off mode operates with same cooling parameters as comfort mode. In comfort mode, cooling is less aggressive than in Sport and Sport+ - perfectly normal.

Hey guys. Soon to be an OG M2 owner here.

Is it possible to have the exhaust in this mode permanently? With comfort mode (with traction fully on)?

Do I need to disconnect the flap controllers?

It isn't a matter of the exhaust valves being open or closed, it is a matter of tuning. The only way to get similar burble in another mode is to get a flash tune that alters the maps for each mode.

There is a plug you can pull off the exhaust valve to leave it open regardless of mode. Just look under the car near the rear muffler. The drivers side if I remember correctly.

Which sucks because it's obvious that most everyone would want these additional decel-pops in Sport/Sport+ because of the significantly better throttle response.

I guess we can't really have our cake and eat it too.
