Reduced power, engine malfunction
This light came on this morning on my drive to work. Scared the hell out of me! I was already half way to work so I continued on at the speed of a Prius! When I got to work I let the car sit and then restarted it a few minutes latter. It appears the fault reset itself because it no longer appeared on the screen or the dash? I guess i'll have to wait until the drive home to see if it comes back on? My car is a 09 135i with no engine mods other than AFE drop in oiled filter?
