Nothing really wrong. But in my experience before I went dme flash tune. I had way too many issues and bugs. Would get 30ff code for no reason. Get random fuel pump over voltage codes, etc.

There are plenty of people who have jb4 trouble free and its everything they need. I made the decision to remove it and get a dyno tune from a expert bmw tuner and love it. No issues ever since, except my ethanol content sensor has recently started going nuts...
