My '14 i3 Rex has about 2000 miles on the odometer and just had the check engine light appear. The light was on for a couple days, and then has turned off. It never flashed when on - was just a steady beacon of concern. Based on an internet search, it appears this had been a frequent problem, but that it was to have been resolved by the March software update (my i3 is running the newest software, having just been leased a couple months ago and also having been at the dealer a few weeks ago for a different, but also common, issue: a replacement of the wiring harness which somehow caused the airbag light to illuminate).
Now that the check engine light has turned off by itself, I am curious as to the view of the experts here as to whether to even bother to bring the car to the dealer for its diagnosis. In the meantime I did hook the car up to an OBD reader, which indicated that codes P1BF0 (that's a zero, not an O) and P0606 are stored in memory. I can't seem to deduce the meaning of these codes, beyond a general ECM failure.
I don't want to waste the time to take the car in if the prevailing view is that this nothing more than a software glitch which has righted itself. But if others have had a similar experience, only to find that a serious problem was lurking, I would be very interested in hearing about that. Thanks.
