I've noticed my parking assist go from bad to worse.
At the moment it is not working at all. I pulled some codes today.
Can I assume this is a matter of just replacing the "mid left" sensor or is that guessing too much?

There is not enough information to make a decision. A no signal/communication fault is indicating just that - there is no signal detected nor any communication. Could it be the sensor? It could. But it could also be wiring or something wrong with the controller for the Park assist.

If it were mine, it would be time for inspection of the possible parts.. that might include getting a wire diagram and looking at what may cause such a problem.
