I installed the Cobb AP V2 on my 2008 335xi about a year ago and everything was great. I flashed stage 1 sport and logged data from time to time. However, now my Cobb does not connect through the OBD2 port. I plug it in and the screen stays dark. I can plug it into my computer through the USB port and it turns on.

Any idea of what's going on? Maybe the OBD2 cable died on me.

I found this post through searching, but it might just be for 2007 models.

Thanks for any insights!

Sounds like a cable or OBD port issue to me.

the pins in the ODB2 port likley backed out, check them

Happend to me before...for 2 reasons:

1st time: I plugged the cable into the AP the wrong way (prong was on top)

2nd time: I had too many maps on the AP and it wouldn't turn on, I had to delete a few of the maps and it booted right up
