I had a similar problem on my old 2012 F30 328i, but they never said it was caused by any of these things mentioned on this thread. When I ordered the 2014 F30 335i M-Sport, I noticed that I couldn't order it with fog lights. The SA told me it's because of the increased air intake needed to cool the engine. Does that sound correct at all?

The MSport has more cooling than the other models. Why would this throw a code?

I don't think anyone has nailed down a consistent repro for it.

+1 And on more than one occasion it happened while I had been in Sport Mode the whole time.

Ever since the new fan and software update last April, all seems well--knock on wood.
