Anyway to disable "Soft Stop" Feature via update?
I drive a 2007 335i sedan, and I have been searching for a while now on how to remove this feature known as "Soft Stop" or "Comfort Stop". I have attempted to get used to way the brakes function, but I have not been able to do so. So I'd like to try to have this removed via coding or an upgrade to my DME maybe? I read somewhere that an update was released that was supposed to resolve the jerk you get when you try to come to a complete stop a.k.a "Soft Stop". Any suggestions would be much appreciated

To disable Comfort(Soft)Stop you need to code the DSC module.
Change the following to nicht_aktiv SST aktiv That will turn it off completely. It is interesting to note that I only had issues with the function of Comfort Stop on early E90's. The system seems to have been refined on LCI models. The Comfort stop on the E60 is transparent in its operation, as well. Perhaps an update of the DSC module can give our early E90's Comfort Stop the more refined feel of the latter versions, without disabling the feature totally. There is a DSC update available for my 06 330i, but I have yet to apply it. I'll report back here if I do. |

Thanks for being so informative ! I feel like our models in specific are actually the epitome of sports vehicles at the time and maybe they wanted to go for a more sporty feel, so maybe they expect you to pound on the brakes like a race driver? Haha. But of course the idea is to get the perfect stop, but alright let me know! I would be very interested to find out if an update would make the comfort stop nice like in the e60s!

I don't think I've ever felt that kick in...

Me neither, although no matter how hard I try to get it to stop so you barley notice it, the brakes always bight at the end. I do know that soft stop has to do with the ABS system so if you don't want it, disable your ABS which I don't think you want to do. You will lose the auto drying brake feature as well.

When it works properly, you'd be hard pressed to notice Comfort Stops operation.
Comfort Stop operates during the last 1ft (approximately) of a light to medium stop. What it does is release the pressure applied to the rear brakes as the vehicle decelerates for those last few inches before coming to a complete stop. The effect of this, is to reduce the jolt and body motion (passenger and vehicle) that occurs during these stops. It smooths the feel of the stop. When Comfort Stop is activated, you can here the rear brakes release. It sounds almost like an electronic parking brake being set. |

I am now in the process of updating my daten files correctly and will the update the DSC module. The system shows that there is a DSC module update for my 06 330i and I'm pretty sure this Comfort Stop has been addressed by it. When I get the update flashed, I'll let you know the results. |

Perfect! I'd be interested in seeing if an update would indeed make the feature less jerky.

I was hoping to be able to enable this on my 2010 X5 and although I have the SST variable in my whole car backup file (set to nicht_aktiv), it is not listed when I read out the DSC module. I would have thought this feature is really just software and wouldn't require additional hardware so not sure why its not available. I do have Auto-Hold which allows you to take your foot off the brake when stopped so I assumed any necessary hardware is already there.

I set SST to nicht_aktiv but the jurky stop is still present. I notice that sometimes it is not there though. I read in the brakes section that it may be the front bushing are worn?

There are two other probable causes for your issue. Both deal with the transmission. The ZF Auto can get a bit clumsy on the 2-1 downshift causing a slight jolt or bump as the vehicle comes to a stop. You can use INPA to clear your tranny adaptations. This will smooth the shifts eliminating the jerk. The jerk can return though. For a permanent fix, the ATF fluid needs to be changed. Another cause for jerky stops is the Neutral Idle Control. It disengages the torque converter at stops in gear to save fuel. Supposedly it can get a little harsh sometimes. Search the forums a bit to learn more about this one and if it applies to your car or not. New tranny fluid cured my jerky stops so I never tried disabling NIC. |

Clearing the transmission adaptations fixed the problem, but like you said it'll probably return. Ordered the pan and will change the oil this weekend.
Thanks for all you help. |

I have a 2007 335i E92, in my DSC module I have SST, but it is currently set at wert_01. When I try to make it nicht_aktiv, I get an error.
I tried wert_00, but it made no difference. Any advice on shutting this off? |
