c127 error codes wont display
Posted: Mon Jun 22, 2026 1:23 ami have a g82 m4 gt4. It has a bmw motorsport build custom c127 display. I updated the files to run an aftermarket IR tire temp camera and tpms. It works perfect. However, somehow it broke the alarm system. When the red leds are flashing for an alarm, it no longer diplays any codes. Can anyone help me figure out how to restore it?
