P1306-62 - Neutral signal learn - FAILED

[lmozdzen]

Hi all,
My start/stop stopped working shortly after I replaced snapped gear changing cable. After a while I decided to buy MES and sort this out. Pressed option to relearn neutral position. It says Completed but Status: Unknown. From that time I always get an error and check engine light plus info that start stop is unavailable. Trying to relearn doesn’t work. Sensor might work as when I removed it from location and turned to the end I get some different error so it knows it’s out of range.
Can someone help me to get rid of it?
Thanks
