Ok, please don't start off by sending me the link to the forum where it describes what it means if JB4 bumps you down to map 4 and how to identify what problem it is with the SES light. I've already read up on that, my problem is my SES light does not blink. My blinkers will blink twice, then there's like a 1 second delay and they blink twice again and I'm bumped to map 4. Last night I was getting the SES light ONLY when I first turned on the car, after a minute of idling it goes away. Recently had to change spark plugs, but even when I had a faulty spark plug my car wasn't doing this, I was just getting that hesitation and misfiring like you get when a spark plug is bad. Thinking it MAY be the HPFP? Have never even had that replaced yet, car sits at 100,457. 2009 bmw 335i, FBO, 93 octane. Can someone please help me out because I'm not throwing a code and I ant figure out what the heck this is. Just started doing this yesterday after refilling my gas tank. After a night of just sitting, still does it. Car was idling a little weird last night, almost like it was misfiring but I'm not getting any hesitation. Idk.

Someone has to have some sort of input on this..

For me that happened once. It was running a little lean... Did you check codes?

I'm having the same issue. Been in contact with jon at bms and we are still trying to fix it. have you changed your user adjustment back to default and are you on the latest jb4 firmware?

In the setting screen it will say '' last safety used '' or something similar. Posting a log is a good way to start. They go a long way
