This happens to me too, but I do not get any change of direction. Slight power loss and traction control firing up, which is the sound you hear.Dsc seems very sensitive fo speed bumps.

If i remember correctly there has been reports of the looming being chaffed in a certain area, maybe this could be your problem, going over the speed bump moves the cable and shorts activating traction control?
I'm pretty sure there is a thread on here somewhere about it... |

In my case I am hoping it is normal and just over sensitive DSC. My Defender is an Oct 2015 Landmark. Low mileage so hopefully not chafing. Commented because veering seems a problem that should not happen. No expertise from me, as previous 2011 Defender did not have DSC.

Balvaig I also have a oct 2015 landmark and it does exactly the same thing.
I don't get it pulling to one side but the DST definitely kicks in as you get the loss of power from the DST cutting in as you go over a bump. Traction control from what I've learned does not cut the power it simply applies the brakes so if you're getting lack of power when you put your foot down that is the DST. Try turning the DST off on the dash and then drive over the bumps and see if it still happens? -2015 Defender 90 XS Landmark- |

The veering may actually be because the speed bump it always happens on is on a bend and the steering wheel is to the right. It is only momentary. Veering is probably too strong a word.
I will have to go into town as they have some short stumpy bumps there in a straight line which will almost certainly cause it to activate. See if the movement to the left happens there. Then try it again with the DSC turned off. |

Good luck!
I'm not too bothered with mine doing it and seems mine isn't the only one, I just think the system is a little overly sensitive. If it gets worse I will have to talk to the dealer though..... -2015 Defender 90 XS Landmark- |

The loss of power is normal, it's the DSC doing its thing. It happens on other cars too just less noticeably because they are, shall we say, "less quirky".
Mine doesn't change direction at all though, and there's no reason that it should really Cheers, David Land Rovers of all shapes S3 onwards… Daily is a 110 V8. |

Yeah it's just the traction control...bip the clutch momentarily and it won't do it,

I've got into the habit of knocking into neutral when I go over a significant speed bump anyway, stops the jerky throttle response when your foot moves around Cheers, David
