2011 LML P104A code

My check engine light came on so I check the codes that it was throwing. It had to do with the EGR Valve, which I thought. I changed it and the code is still there even though I cleared it. From reading further, I guess that I now need to change the EDR Bypass Cooler. Can some one snap a picture of the location for me. I just want to make sure that I get the right part and know where this thing is located. I am going to do the work since the dealership wants an arm and a leg to do the work. I have 200863 miles on the truck.

Thanks in advance
Mark

You may want to consider actually diagnosing the problem, like making sure the various parts of that system are getting power and ground, otherwise you are just throwing parts at it hoping something will stick.

Maybe also try searching this forum and googling your code for how others fixed this code.
