Unfortunately I never looked at the “interim” fix (68483334AA) one. I can tell you the one just installed in mine about two weeks ago with the part number starting with C (don’t have it handy) says 2111F and the unit has a manufacture date of 2/10/2020Kentuckydoug , what does the sticker on your EGR say ??
here are images of EGRS posted on the site , so far I can only '' assume ''
the 2111F seems to mean new model , in the past it was 2064F ,
again this is a theory , the new model EGR looks exactly the same as the old ones from the outside .
last image is a 2019 that got a recall EGR before it could be sold .
if anyone can confirm this to be wrong ,,, we will need to find another way to tell the difference .
