I'm not 100% sure on this but I remember reading somewhere that the updated EGR valves are supposed to have a red dot on them. Mr. Dalton can you verify this?

Thanks,

The Factory put out a Service Campaign on the EGR upgrade and these were to be done on any car that came in for service with a EGR fault. Once the Valve was changed , the Tech was supposed to put a dot of paint on the new egr to let any subsequent Tech know that the Campaign had been done on that particular car. The reason for this is the factory never changed the actual part # on the EGR with the new diameter stem, so the paint was for ID purposes. The problem is many got changed , but the paint dot just did not get added .
So , when one is doing a hand vac test, he also wants to do a snap shut test to see if the valve hangs up at all............

Mr. Dalton,

Thanks again for sharing your knowledge.
