No idea but am wondering if that was the reason my Forscan profile load showed so many DTC’s. I have been running with this incorrect VIN for months and never noticed anything weird. Got back into Forscan to increase the bass and volume of my stock 6 speaker radio and just started looking in all the drop down modules out of curiosity. Saw the VIN for the first time in BdCM and corrected it. Then saw it again in at least 2 other modules but it was correct in them. Will be driving it tomorrow for the first time since making several changes, hoping nothing goofy happens.I never inputted my VIN anywhere and eveyrthing still works. Is that important? What does it do?
