Okay... false alarm on fixing the P1515-- sort of. While trying to get my readiness done for emissions, I pulled up the BMW codes on my Foxwell. The SES light is off, but along with now the Bank 2 Sensor 1 O2 sensor showing a failure (ironically not the no longer the Bank 2 Sensor 2 is showing a failure), I still see a 2F80 "DME: System time, plausibility" error, which I assume is the P1515 on OBD-II. This seems to be a pretty rare code, unfortunately, and I no longer blame the dealership. Also unfortunately, it seems this points toward DME failure. I'm also wondering if the DME isn't talking to either bank 2 O2's. So... at least a $400 repair at someplace like the-ecu-pro.com. Damn it.


If somebody has a recommendation of what else this could be, PLEASE chime in.



Are you guys ever threatened to set your POS Nazirocket on fire? I am close. I should have bought a soulless Toyota.
