Check Engine light stays on. No other symptoms. If I reset the computer by disconnecting the battery, the check engine light eventually comes back on and stays on. Sometimes this takes weeks... sometimes...

you should have scan done for fault codes
but you could inspect the throttle body for carbon deposits and clean as required first and see how it goes

Check engine light came on codeP0401

Yes, this is a carbon issue. the EGR valve is very sensitive to carbon deposits. i suggest using pressured air to clean out this throttle body before you purchase another valve. it will keep rejecting the egr if its not cleaned.

Check engine light keeps coming on with code 332 egr code.

The Egr ports are plugged in the intake. Remove the throttle body elbow behind the throttle body, and clean out the carbon. I can walk you through it if you need me too. This is common on the 4.6
