I have read many threads of you others having had the reduced power engine malfunction on your M's. Well I was hoping I wouldn't have to experience this but I too did this morning. I started the car no excessive turnover or lag starting. Pulled out of garage and within minutes at the first stop sign my X5M was idling super rough for the first time having it for the last year. Continued to do so till I got to my first destination and shut her down. After a re start immediate rough idle again followed by the CEL and the engine malfunction and reduced power message. I shut it down before pulling off restarted and shut it down again and one more re start and pulled away with no CEL light and back to normal idle. Any others that have experienced this in similar fashion where the light went away as well as the rough idle?
