So the headlight coding has been extremely exhausting. Me and a tech are learning this for the first time. Yesterday we found out we had the wrong cable that only worked on older bmws. (Something about bridging pin 7&8). Tonight we got the correct cable.
We tried using the old frm first since everything but the high beams worked. When we tried to change the vo and production date in the frm it wouldn’t stick. It would keep going back to the original build date and vo.
Tried a new FRM3 everything except the high beams worked. But we have lighting and passenger airbag/restraint warnings
