question Zetor Forterra 140HSX 000108 fault code

My Zetor Forterra HSX140 tractor randomly displays the error codes 000108, 002061, and 500002, and it reduces power during these times. If I disconnect the power and restart it, the error disappears, and I can continue. What could be the issue, and how can I resolve it?
The tractor's AdBlue system is already disconnected; It has an electric dosing system..

The Forterra HSX mod. 2018 error code list I have begins with error code 520192 - so I cant answer your question and may say the best will be to ask a official Zetor dealer. Sorry.

I have a HSX 140 too. What year is yours?

I accidentally found out what the problem is for me. The previous owner disconnected the AdBlue system, which was probably done incorrectly, as that’s why it’s throwing the error code.

I did ask what year was yours? but with that answer, yours is newer than mine as mine has a DPF filter.
