Updating the BCM just makes the approach light on/off setting available, it doesn't disable them. You still have to get the dealer to disable the approach lights or make the change yourself with forscan.
Mike, I don't think anyone knows. Interior dimensions are different, between the generations. So if it is custom made, then no. You could probably cut and weld, and make it work. Your best solution is to source shelving made for your model. Or fabrication.
Actually, that's not true. There are reinforced places in the pinch weld where it is triple thick and those are the only safe jack points. Jacking where it's just the two thicknesses welded together could crush the rocker panel
If you keep the jack within about 6 inches behind the front wheel and 6 inches in front of the rear wheel, you're pretty safe, but the bet practice is to double check to make sure you're jacking at the reinforced spots where there are 3 pieces of metal welded up and not just two
