I own a 09 535i and recently got a check engine light with engine malf reduce power.
I stopped the car and restarted it which did the trick and went away.
To make sure everythin was alright took it to a dealer and have them check it out.
They told me that they dont see any code of it and it might of fixed itself.
Is that even possible??

yeah i.e if you leave gas cap not tightly screwed it will fire CE but once you fix it - it will go away....

Get JB4 and check yourself. Enjoy the improved performance, and self diagnosis.
