Esc Off = Comfort Mode ???
Here is a thing which bugs me all the time: whenever I turn OFF the ESC, I have a feeling that car is secretly switching to comfort mode, and it doesn’t matter if I turn it off on sport or sport+ mode. I can also see it when I select sport+ then hold ESC off, then the car is with full ESC, so then I’m changing the setup on drive select either up or down, it looks like it starts from comfort mode. (one down=eco pro, one up=sport, where first position was sport+)
Hope this makes sense, and that some off you can explain, or confirm this. PS. It’s a 125i with sport auto

This car is pretty good staying at whatever mode you are in. I only switch it DSC OFF in SPORT+ and it stays there. The throttle responses should also confirm that. Hope we at least agree on the SPORT + mode

No, it does not. If you go from Sport+ to DSC Off, it is back in Comfort Mode. This happens to all modern BMWs, not only the one series.

While we are on the subject, have anybody tested what modes the electronic fake differential is activated in? It is pretty much impossible to tell if it is enabled as long as the traction control is on. With our rather modestly powered 116i, it can also be tricky to test it in DTC (Sport+) mode, but it seems to me like the differential is still open there. I get some chirping from the inside tire when powering out of tight corners, and the car does not rotate into the corner under power as it should with ediff enabled. But I am not sure, as DTC does not allow the car to provide its full cornering potential.
With DSC Off, the ediff is definitely activated, and working surprisingly well. I think this (ediff only enabled with DTC Off) is also compatible with the rather vague descriptions in the owner's manual. Last edited by ovekvam; 06-18-2013 at 04:11 PM.. Reason: Fixed some typos |

It's not full comfort mode with DSC Off. The throttle response drops to comfort mapping but the steering defaults to sport (If you have servotronic or sports steering)

How about the suspension? I've heard it goes to comfort mode as well on the Z4. How is it on the F20/F21? Our car has non adaptive suspension, so the only variable factor is the engine response.

Suspension goes to the stiffer setting with dsc off.

So when I use SPORT + & DSC OFF
Throttle = Comfort Suspension = Sport Traction = Yet to confirmed? (I did two donuts in the rain, drifted twice, does that represent anything?) With DTC it lets you loose traction slightly. I am going to test it out soon. |

@Subnasty: You are correct in the the car is switching to COMFORT.
@ovekvam: Thank you you are absolutely right too. My cars were not BMW other than the E30 325i, which predates all these electronics. Nevertheless a little test was carried out. I went up a steep climb in SPORT+ while pressing on the traction button to get to DSC OFF. Sure enough there is that sudden dip in power when DSC OFF, suggesting it has gone into COMFORT. In fact in any mode other than SPORT+ if the Traction button is pressed it defaults to COMFORT. SPORT+ is the only mode that does not go to COMFORT with Traction OFF (off by default) In fact if you press traction off in ECO PRO it goes to COMFORT. If you want DSC OFF, the power mode is COMFORT and COMFORT only. We didn't test out the chassis as it will take longer, and we do not have the road available to us. I guess BMW design the things to work out like this with safety in mind? Last edited by westphone; 06-18-2013 at 02:45 AM.. |

Yes, I think BMW is not trusting the customers to handle the more abrubt throttle mapping with no DSC to help.
I have also been doing some testing, and I have come to the conclusion that the available power at full throttle is the same in Comfort Mode as in Sport Mode. The pedal mapping is however very different, so the power is significantly different at half throttle. It is easier to modulate the power in low grip conditions in Comfort Mode due to more pedal travel, but more difficult to overcome turbo lag in high grip conditions. |

Yes, the turbo lag was more difficult to overcome. It has been strange for me to press on the gas pretty hard before really having to turn if I were to initiate even a little drift. I guess there are many people out there eager to have SPORT+ and DSC OFF available at the same time like you mentioned.

Even if I'm in comfort and turn DSC off the steering changes to Sport mode.
I believe it doesn't matter what driving mode you are in. If you turn DSC off in the f20/21 then you get.... Throttle mapping - Comfort Steering - Sport Suspension - Sport Auto box - Comfort changes unless moving the lever to DS. Cheers Lee |

Might be always active but if other stuff interrupts power etc first you wont notice much.

There is this product in my region that is very common. It makes the throttle response more aggressive especially early on in the paddle travel, so COMFORT will be very similar to SPORT. It does so by sending fake signal to the computer. They didn't tell me what happens in SPORT, though. I guess for someone really want the throttle response with DSC OFF here is a remedy, thoughI wouldn't install it personally. (sorry not trying to plug any product, just mentioning this thing exists )
