Mine does the same!! 05 MCS car idled horribly(did not die) i took it in for a software update to V.37 and now the car idles poor then DIES. called MINI and V.38 is supposed to fix that problem. I say it prob. won't fix it, but will take it in and give it a shot.harold said:When I try to warm up the engine of my 05 MCS in the morning, it will suddenly go to way down in rpm, sometimes it even die on me. My buddy's 04 MCS got the same experience, anyone experience the same? Any suggestion?
