I just received this code, along with 2E8D (Intelligent battery sensor, signal transmission). This was after my E70 sat for 5 days without driving (also note that overnight temps have been getting cool). The battery may have dipped below a certain level causing the code... that's my guess. I cleared the codes with my Carly and so far so good. Will update if they come back.
