There's going to be far too much information to post suggestions here It it had happened to me, I'd have done an internet search for something like T6080 error codes and follow up there to see if there's some kind of common thread to each one.
Failing that I'd have searched for forums specialising in New Holland tractors (there's several) and posted a question there.

Having said that, here's a result I found that may help:
