Do you have a video for removal and cleaning of EGR related issues?
Thanks.

Hello,

We do not have a video, but I did find this diagrams showing the EGR and how to remove it. To clean it use carburetor cleaner, coat hanger and shop towels.

Here is a video on how to test the valve:

Check out the diagrams (below). Let us know what happens and please upload pictures or videos of the problem.

Cheers, Ken
