Changing the steps / mm can be done without firmware modifications, but then you have to correct it with every print job.
You can do this in the start code section in your Cura's printer definition:
G92 E<steps/mm>
Disadvantage is that this gcode now only works on your modified printer.
The UM2+ / UM3 feeder wheels do wear down. When tested with composite material, just printing 1 roll of filament was enough to cause extensive wear on the feeder wheel. That's why the abrasive resistant CC-printcore is not supported on the UM3. The S5 feeder wheel was hardened extra.
Perhaps you can get a replacement feeder wheel?
