hey all. i have a CVT Cooper and im having a slight problem with it and im hoping u guys have had the same problem and are able to tell me what is the cause of this problem!!
It started about 3 weeks ago wen i first got me car. i decided to put regular unleaded fuel in my car and it was also the same time i put my K&N intake filter on. i noticed the car was running as sick as a dog(really laggy and not very responsive) so i decided to put my stock air filter back on to determine if that was the cause....it wasnt. i then put premium unleaded fuel in the tank and then the car was back 2 normal and it was amazing how quickly the car responded 2 the change of petrol(i was told maybe the computer remapped itself)since then the car has been going GREAT :smile: up until last thursday(5 days ago). it isnt revving freely or response at all, wen i put it into SD from D it just doesnt rev(normally it revs right up until redline, it now struggles 2 get to 4500rpm) and it also stalled this morning!! i used 2 enjoy driving my car now i honestly dont!!
im going 2 the dealers in two weeks 2 get my transmission reprogrammed and i told them about my new problem today and they said this problem will cease once they install the updated software. has this happened 2 anyone b4? and if so what is the actual course??

 

Howzit, SYDMINI! My CVT stalled twice early on (was running on 89 back then). Had the software upgraded soon thereafter (& have been on 92 since, no less ...learned my lesson for good). Since then, my CVT has been smooth. Well, on real hot days -- after I've parked in the sun & had the a/c blasting while driving off -- there has been the occasional power struggle. Overall though, I've got no complaints. I love it! Hey, I've got a question for all you CVTs: does yours struggle from around 95 to around 105+ mph?? Mine takes a while to get to the latter. However, getting to around 95 is a breeze ...

 

hey mate. havent noticed the struggle in the kmh u indicated. wats 89 & 92? please excuse my utter stupidity and ignorance!! :smile:

 

You've driven your MC at 105+ mph? Where? You'd run out of road in a hurry in Hawaii.

In Hawaii our fuel is 87 octane for regular unleaded, 89 octane for unleaded plus and 92 octane for premium.

*SYDMINI: my bad for not clarifying those octane details . Take it easy...

*minihune: hey, Doc! This is not good but when I find a stretch with no cars around... I let 'er rip. Dumb, yeah? Can't wait for Spring Fling . How's your recovery coming along, pal??

 

thats cool. i currently live in Sydney

 

*SYDMINI: Sydney?? That's awesome

*minihune: oh yeah, I do run outta straight road (I take no chances around bends). Where, you ask? I prefer to not say on NAM . Also, I truly do make sure that no one's around...

Only been to Hawaii once,last April before my MINI. Would like to Motor with NAM someday. If I recall correctly there was a patch across the interior on Oahu out by the Dole plantation that would allow some speed.
