The fuse is inside in the car, in front left corner, passenger side:

So the original location of the items will not be relevant anymore. In my case, he has thrown in various airbag wiring, removed the airbag screws, etc, the car is completely different than OEM. The airbags do not work anymore for a change.
The front auto leveling sensor is behind the front wheel:

If there is a fault recorded, you should be able to read the DTC:
