Thanks W///. Do you know if the diag tools at a shop live Advance will suffice to clear out BMW-specific codes? Just for reference invoice says codes are 2B22, 2B16, and 2B5C. Are those proprietary?
Although I am a software engineer, I admit to not knowing jack-sh*t about the many CUs in cars and related tech. I guess it is time to change all of that.
