Technical P1305-62 Neutral Position Sensor

[All60Horses]

So I broke one of my gear linkages and replaced them. Ever since I've had a Start/Stop error which I narrowed down to a faulty neutral position sensor from me being heavy handed.

I've replaced the sensor and tried to carry out the learning procedure on MES, but a message pops up saying 'UNKNOWN', and there is no parameter for the status of the neutral position learning in the parameters page, despite what I see online suggesting there should be?

Anyone got any ideas? Have my MOT coming up soon, and it won't pass with the MIL on...
