Deutz-fahr error codes

[dim_tsile]

Hello everyone!
I bought a Deutz-fahr 4070E and suddenly pops up some error codes. Τhe most common code is M358. Some other times its M525 or 521 or the three combined. Sometimes they go away while i'm working and others only if i turn off the tractor. There is nothing like limp mode or something. It works fine while there is a code on the dash. What are these codes indicating;

M358 speed sensor
Mismatch between Engine RPM and Ground Speed

M521 Range Lever
Signal error from High/Medium/Low selector

M525 Gear lever
Signal error from the 1–5 speed selector

This is what I was able to find for those codes.
Hope it helps.

Would be interesting if they shared a ground connection. I'd look into that.
