At 1,600 miles on my new Countryman All4 S my turbo failed on Monarch Pass at 11,000 feet above sea level. The engine warning light came on and the cars engine was running fine, so I limped the car over the pass and down the other side, driving another 50 miles or so. After the car was parked overnight, it started fine and the warning light was gone. I drove back over the pass without issue (but took it easy thinking it could be a thermal problem with the turbo). I took the car into the dealer and they (of course) told me that they could find nothing wrong and the computer did not store any fault, nor could they educate me on how this could happen. The issue has been gone and I've driven over 1,000 additional miles without incident. However, ski season is approaching and I'm a little concerned about it happening again. Anyone technical enough to tell me what might have happened or how to avoid this from happening again (though I would prefer it to be fixed)? Anyone else have this issue and did you resolve it? Thanks for the help and advice!!!

 

the issue is the O2 sensor that is not weighted for high altitude air. That is why you have a check engine light , it happened every time I went to Mini in the mountains

 

Thanks for the reply rossigian. Is there an adjustment or is it a problem I have to live with?

 

+1 The MITM Schomp team dealt with that very issue telling me the same thing. Haven't seen that little yellow gremlin since.
