2006 Jeep Liberty: I have been told the EGR system is not working

Customer Question

i have a 2006 Jeep Liberty Diesel.The engine light is constantly on. When I have taken it in I have been told the EGR system is not working. They repair the problem the light goes off and comes back on in a week. I no longer have a warranty and I do not believe the diagnosis. What can be done to get this engine light off and keep an eye on this RGR issue?

What code are you getting from the computer?
Customer: replied 4 years ago.
Does AJR 2815 mean any thing. I took this off the paperwork on the repairs. I have them all and this code is repeated on each job concerning EGR.
