Last night my service engine soon light came on while driving home. My car has been FBO for about 9 months, with no new or recently changed performance mods since that time. Performance feels normal to me (no limp mode.)

Codes I read off of my JB4:
30
Just those two digits. When I set the JB4 to read codes it goes to 3, then 0, then the turn signals blink twice. I'm guessing this may not even be a code, just something related to theJB4. Sorry, no USB cable (yes, I know, I am bad and I should feel bad.)

2F6C
This appears to be because of the "golf tee mod" which was done over a year ago. Probably not new.

2C77
2C78

These both seem exhaust related according to my searches. I have catless dp's but I've had them installed since last August and have never seen these codes before today.

Any advice?

Thanks in advance. I have searched on this topic, but none of the situations I encountered seem to match my own (spontaneous SES light with no new mods recently)

Ill ask a stupid question but did you accidentally turn off auto clear?

Do you have the dp fix installed?

Mine has done that once in a while and then disappeared after a little more driving.

The 30 "code" just means you have three codes stored.

I was wondering about that after I got to work this morning. I can't imagine doing that by accident, but I was thinking I should go back in and verify that autoclear is in fact enabled.

I cleared the codes manually before driving to work this morning, and the light didn't come on during my approximately 25 mile commute.

Great to know, thanks!

I wouldn't worry unless it reoccurs again. My car throws random codes once in a while and never again does it
