To be honest, I haven't noticed an appreciable difference in time it takes to warm up in Comfort vs. the other modes.
One of the reasons Comfort mode runs "hot" is to increase efficiency (better combustion that that temperature vs Sport temps). Personally I like to keep temps a bit lower despite the efficiency loss - in general more heat causes more wear. Although I don't know if it actually makes any appreciable difference in engine life between those two temperatures. |

I’d like to see that, because MDM definitely runs hotter than sport+ on my car.

Would be good if others can confirm. Seems crazy MDM would have less aggressive Comfort like cooling. |

Guess all the replies solved this mystery, and sounds like a good reason not to use MDM at the track.
Altho, if you’re pushing the car hard enough at the track to need the extra cooling, you’re probably already using DSC off. I use MDM in the rain, so no cooling worries there. Last edited by ZM2; 02-02-2019 at 05:33 PM.. |

On most BmW’s When you WOT it will raise the coolant pump speed thus dropping temperature ( also open thermostat more ) and increase the oil pump |

So I'll keep using MDM to warm up the car then.

I thought about that, but I’d be tempted to have fun and get the revs up while in MDM and the engine is cold.
I wonder if there really is no warm up time difference bn the modes? The more aggressive cooling modes drop temps to 170-190F. Surely the “OK” temp is below that? |

Just realised this accidentally today when cruising at 120km/h. Came accross this thread when looking in the internet to double check.
I also noticed that, regardless of the driving mode, the coolant temps will also drop from 100-105ºC and stabilise at about 85ºC when exterior ambient temperature reaches 30ºC. |
