Hi. My backhoe lost power, got slow ride and operating, you cant do 2 moves at once, because it wants to die, rpms goes down etc. I got error 0 2791 - 7 X . What is a problem ? Is it EGR problem ? Hard to find anything. My DPF has been cleaned, so I assume is ok.
Need more information to start. Machine Serial Niumber.? Did the low power problem start suddenly or has it been getting worse for some time.? Have you checked the condition of (or changed) the fuel filters.? Can you take a photo of the panel when the Error Code is showing and post it here please.
