Mein Auto: F31 xDrive Msport
xDrive Judder

I used to have an old Subaru Legacy which was wonderful in Scottish ice, snow, greasy rain drenched roads and rough tracks. I've just sold my 120k E46 which has spent many a week stuck in the drive because of ice/snow that my wife's Volvo has had no problem with. So, I've just bought a new F31 xDrive hoping for similar dodgy road performance with the added BMW experience.

I've not had a chance to test in slippery conditions yet but do find that the xDrive seems to judder whenever a wheel goes over a step, stone or pothole. It feels like the electronic control is over-reacting to momentary loss of traction on a wheel. Has anyone else experienced this problem? Is there anyway of contacting BMW to encourage them to tweak the control laws in the software?

I bought the adaptive suspension too - my wife (who hated being a passenger in the E46) likes Comfort mode - and Sport gives a really worthwhile improvement in overall handling.

The system is way out of control. It kicks in on every bump and pothole. I dont have DHP, maybe it has to do with xdrive.

I suspect that what you're feeling is the stiff RunFlat Tires rather than anything to do with the TCS. Has the yellow triangle been flashing on the instrument panel? If not, TCS/DSC isn't reacting.

I had to drive into Philly today. Good thing for DHP. I95 in SE PA is a horrible road for sport suspension. Just horrible. I really like the tighter sport suspension, but it's really nice to have the option of switching to comfort.

i think he is talking about loss of traction. In my case yellow indicator goes off all the time. If i go over a bump or pothole at speed above 20 mph, it kicks in. It's way to sensitive
