Hi Daniel, still got one?
I have replaced potentiometer.
Costed….. 0.5 USD, not exactly same but fits. Some tears, blood, sweat, assembled, adjusted, working like a charm. Original potentiometer in the centre of the wheel was a cheap, plastic, nothing has been left from the original circuit, caused that steering has became woobly, and not possible to drive exept in drift mode, finally stopped turning to the one direction.
If you got soldering skills and some tools for cutting plastic (knife can hardly fit) you can do it by yourselves.
10-12 kohm resistance and ability to turn in all directions without limits - this is prerequisite for potentiometer.
Mine got a block preventing turning more, opened it and removed piece of plastic that was a blocker.
Good luck.
