Hazard lights flash map 2 with JB4 tuning

Jaybrickz · 10-16-2018, 10:56 AM

Has anyone experience something similar? I got a JB4 tuning in my e90 and it's really fast, especially being in map2, but one thing I noticed was the hazard lights flashing but everything still functioning as expected. Any idea what thise hazard lights means?

Constantly flashes? Mine only flashes once warm

Maybe it's the shift light? Check menu option #3 on the steering wheel controls and see what RPM it's set to. According to the JB4 controls 0-6 is active, 7 is disabled. I turned my off as it was confusing me. I think another possibility if the hazards flash is you are misfiring but I would expect you to get thrown into Map 4 if so.

Def check the shift light settings and go from there though

It could be the shift indicator feature that's paired with JB4. If it hazards flash twice, it'll throw you into map 4, which is the safety map
