I have about 17k miles and just had the 3rd egr valve replaced!

Anybody have this problem?

That's a new one for me. How do you know it's gone bad?

Check engine light came on. According to Cummins, it was replaced once before I bought it. Then in March the light came on and it was replaced by a Cummins shop in Virginia on my way to Florida. On my last day of the return trip in April, the light came on again and the Cummins shop in Newburgh, NY was told by Cummins to replace it. They claim there is a problem.

You really need to have them check your p&D tubes, they get stopped up and the light will come on then as well. Sometimes the egr cooler get water in it and the causes the p&d tubes to get gummy.

SOUNDS LIKE YOUR EGR COOLER IS LEAKING WATER INTO EGR VALVE.HAVE THEM CHECK THIS ,IN MOST CASES THIS WILL SOLVE IT.

So...Oldhiker: Did anyone ever explain what a "p&D tube" is?? Some of us mechanically challenged guys don't know the abbreviation and lingo. Steve

Steve, I am also one of those guys and, no, I don't know what it stands for.

Just to bring everyone up to date, I now have 22k miles and have just installed the 5th egr in this, counting the original one. Since I am now in the third year of my warranty, they now charge a deductable of $100.

Now I am getting mad. Since each egr valva has been replaced by a diferent service center, I can't blame the techs, I can only blame Cummins for a poorly designed valve.

I wanted to bring this up to see if anyone else is having this type of problem.
