Well, that's too blurred to see, and here they have a different printout.
Can you tell me what the max allowed is, and what yours measured, for each of the 3 catagories??

ie: HC (ppm) max 106, yours 99
CO (%) max 70, yours 0.14
NO (ppm) max 762, yours 1000

If your NOx was over the limit, there's a good chance the EGR system is the trouble. These EGR valves are usually tough, and not the cause. The passages get clogged up, and that needs checking. The EGR valve transducer goes bad more often than the valve.
