If you really must know...disconnecting battery does not
reset the ECU. Ask any experienced tech at any BMW dealer. It's an urban myth. The trick will work with OBD-1 cars and some early '96 models.
Resetting the ECU requires a GT1 to do the proper job. |

I believe you when you say that fully resetting the ECU is impossible without a BMW tool.
HOWEVER, there are settings that are reset when you kill the power.

I have never tried it and, as far as I can recall, I never claimed it to be true.
I think it was zcasavant talking about doing it in that one thread at the Fest and I know our Nick also claims it works. I have no idea. |

Yes, Nick. We discussed about soft and hard resets. For E46, disconnecting battery resets the throttle adaptation values. That's it. ECU will still retain its own adaptation values.
I strongly recommend any of you to ask the dealer to do a FULL ECU reset. Trust me. The car feels different.
