I've replaced my EGR valve 2 or 3 times on my 2008 Chrysler Town and Country. All about a month or two apart. They came with a lifetime warranty, and the store doesn't have any issue with replacing it multiple times...but with so many failures, I wonder if the EGR valve was good, and its some other problem. Is there a way to test the EGR valve, or the electrical connections? So far I have been ignoring it for a couple years now, but the remote start won't work if the check engine light is on. Also I am not alerted to other issues if the check engine light is always on.
