Has anyone had success updating their SA code to allow Xentry to program new features for their Benz?
I recently installed a tow bar / tow hitch with the TCM, which included pulling up the interior to run the wiring harness to the center fuse panel and then all the way up to the drivers foot well area.
The issue now is that we've been unable to 'add' the trailer hitch via Xentry because it states that the base SA code doesn't allow it thus the drop down to program isn't available in the VMI options.
