I had reported that I had the v36 update done about 2 weeks ago on Roxy and I would say that it corrected about 98% of the problem. The shudder when slowing is totally gone, but not at idle, at least not completely. The *stumble*, which was the big one, does appear to be completely fixed. Of course, all of this only happens with the A/C on and it has to work (+65 degree outside temperature). I’m still watching it to see if it gets any worse or possible better. I think a call into MINIusa might be in order, as well as a call back to my service department.
