BMW MHD(?) Problems?
So just last week I performed a JB4 Backend flash by MHD. Car was working great but I did notice that the exhaust sounded weak at first. Throughout the week it sounded weak too. (Maybe the disable cold start option). Today I was driving and I floored it. The check engine light came on and I noticed the car engine was like shaking. I pulled over immediately. I shut my car off and then I waited a minute to start it back up. Once I started it back up, the startup sounded kinda weird. The engine ran a little then it shut down. The battery was still running but the engine turned off. This loop keeps happening and I don't know why. When I drive it, It goes for 10 seconds and shuts off again. Please help me. Any suggestions?

If so then check the settings in MHD. I had a similar problem when the tmap sensor option was not ticked in the MHD option menu |

OP, did you do basic maintenance before installing tune?
hint, replacing spark plugs, ignition coils, walnut blast cleaning and solenoids? I am not sure how old are these components in your car. |

OP, as stated before, flash back to stock and see if the issues go away. Then go from there. |
