The EGS on that should have a couple of small electrical plugs on the front of it. It's possible that one or both may have come unplugged or damaged the wiring. I would remove the whole selector cover and take a look. If the indication for park, drive, reverse, neutral isn't showing on your instrument display when moving the selector, then your EGS isn't recognized and doesn't know what gear it's in and will put you in limp mode.
