Default Help reading codes - 12-27-2016, 07:38 AM

So I have a few codes that just popped up. I recently went to N55_ISO_13 from version 10 and a few days later my check engine light came on. I have a 2011 n55 135i with a *** less **, Burger intake, JB4. I also ran 3.5 gallons of E85 one time that the codes popped up and twice i was running just 93. Car runs fine as far as i can tell.

I have tried to google the codes with little success so here i am.

Here are the codes if anyone can help me and let me know what they are.

2EF2
E4C3
1062
C903

I have cleared the codes 3 times now and they come back. Not all the codes come back after every clearing but in the past 3 times I have read and cleared the codes those were the total of them.

Thanks for the help in advance.

I did check there. It did not have anything on those codes. Im not sure if using the jb4 app on my phone to read the codes makes a difference.

App wouldn't have anything to do with it. If the codes aren't listed I'm not sure what to tell you as they don't look familiar to me.
