I figured it was carbon buildup issue so I had the egr valve cleaning service done. After the cleaning service the egr check engine light code went away for 3 months but recently returned a couple days ago. I'm pretty sure carbon isn't the issue after just 3 months. Could the egr valve itself need replacing now or what?
