I have a couple of questions re v36: Should everyone have v36 installed just because it is the latest version of the Mini’s operating software? In other words, does every car need the new software? Are there cars out there that are running just fine on older versions of the software? Are there any downsides to having the latest version installed just for the sake of having it? The reason I ask is that my 2004 CVT does not appear to be experiencing any of the problems I have read about which are associated with earlier software versions?
Theres the quandry, if it aint broke, then tell your dealer not to upgrade when the service call comes along, and make sure they understand. In all honesty the upgrade should only apply to a range of VIN numbers, those not in the range should not be changed. I hope the diagnostic software is aware of which VIN's are affected, and only applies the upgrade to these, it would make sense , and I think the BMW/MINI are switched on to the best practice , I'll check it out , if its not as it it should be I'll post a cautionary note here.
Mini USA claim that the YoYo is a characteristic of the car - even after v36 - therefore ALL mini S models will exhibit step acceleration [yoyo] at 2800 - 4000 rpm - with a specific torque loading on the engine. [like when you are accelerating through the most useful part of the tourque curve in normal city driving]
Those who frequent these halls who claim that their S model cars don't have a problem, are either totally insensitive or in denial.
Or [and I think we all know the answer to this one] BMW are BSing us to save themselves a few bucks.
Those of us who got a bad one are screwed - and good for those who got a good one.
I don't want any assosciation with a company that will knowingly sell you a car with serious driveability issues and then turn their back on you. [to the extent of lies and deciet in Lemon Law proceedings under oath, to avoid having to do the right thing and delivery warantee]
This is one car they will get back.

DS/W MCS 3/03 Awarded LEMON Status The yoyo is deemed to substantially impair the value of the car - by the FL Lemon Law. 4/14/04 In the end the LEMON squeezed itself so BMW can suck the juice.
I think the Siemens sourced adaptive software is so complex that they can't even determine its behavior once downloaded to the car. It is pretty daunting as to why some cars have severe problems and others don't, using the same exact hardware and software.

Had v36 installed today. No help. new MCS 2004 , now 1800 miles.
Just to repeat, yo-yo occurs at partial throttle 2500-3500 rpm, 2nd and 3rd gear only. More spirited driving and keeping your revs higher (or lower) avoids the problem. Most of the time it is just noticeable. For ex, yo-yo would not be easily detected on a bumpy road. Harvey
MCS '02 - 13K miles. Stumble 100% fixed; Yo-Yo 100% fixed (both were very obvious before V36)
Note that i do have normal stick-shift mechanical "bucking" of the car when suddenly lifting off the throttle in 2nd and 3rd... but the weird partial throttle yo-yo, where it seemed like the engine SW was trying to compensate for something, is completely gone.
