I have a used but freshly cleaned (0 miles since power washer) EGR cooler for sale. $140 shipped in CONUS, paypal preferred. I had a spare which I intended to use to reduce downtime when I did mine, but over the long weekend I just cleaned them both and put my stocker back on since the downtime wasn't an issue.
Adding pics and dropping price to $130 shipped, hard to photograph the inside but I did my best to show how clean it is.Also I can include the EGR Valve and the valve elbow if desired, with the caveat that I opened the actual valve itself and the phillips head screws that hold the valve assembly together will need to be replaced.
