Error multiple sensors

Hello, Maybe someone has had this kind of error before, or may be able to estimate what kind of problem it might be. I once added a diagnostic report to a free workshop, which reproduces errors of several sensors. I was in four different workshops, each time a different diagnosis. At Land Rover OS, I should exchange the control chain for € 4300,-, but no indication in the error report. I had made a request about this. Is there any way you can think of it, but you can’t get any feedback… Can someone explain what possible mistakes they may be?
