I have the downpipe fix. I read the instructions wrong and set it too low. It needs to be turned up. Terry @ bms told me I need to check the code and adjust accordingly. Then I have to reset the light and adaptations. Local BMW meet on thursday someone will bring an OBDII scanner to clear the code. I have to figure out the adaptation reset with INPA. After the adjustment I hope all will be well.
