If by TSB you mean the transfer case odor that smells like a sulfurous rotten egg, then I can help you. I had the same issue with my 2016 MKX 3.7L. Lincoln tried to fix it 6 times over two years and failed. I was about to lemon law the car, but my salesman convinced me to accept an upgraded model 2018 same engine at an extreme discount to help with the lost value. That one smelled as well, so I got a 2018 2.7L turbo and that one is fine. This happens to multiple Ford products and they truly do not know why other than some transfer case fluid smells when you unleashed it, and the smell gets into the vehicle when AC is on. My dad’s new 1975 Gran Torino did it as well! I would try to change that fluid and if that doesn’t work, maybe trade it in.

I’ve been considering a 2017 Edge 2.7T for my daughter and currently own a 2018 MKX. The issue you refer to has not been picked up yet on any of my 3 previous Lincolns, but I did see something similar when researching a 2008 Escalade. the headlamps get the same issue and run about $1000 per pair before ballast, bulb, and installation. You might want to look at aftermarket housings, as well as if there is a lower cost OEM which fit your vehicle.
