Just got the new M steering wheel installed. The same one that was being sold by the fellow on here a while back. He turned out to be legit. I have the heated steering wheel and lane departure vibration features which work great. We had to take the wiring harness/modules from the old and put it in the new wheel. There was an error code which popped up saying that the ACC wasn't available but that went away once the X5 recalibrated itself. Now everything works great.
New on top and old on bottom
