P048D & P048E Codes thrown

[QuickOne]

'21 JTRD threw P048D & P048E today. Truck has 2200 miles on it. They seem to be EGR related.

Anyone else get these?

Given all of the parts delays, I fear it might be sitting at the dealer for a while.

Welcome to the diesel world.

When I first retired from the military I was a maintenance manager for Caterpillar and then Detroit Diesel, EGR valves on diesel engines are high failure parts. Darned if I know why, but we would put one into a vehicle and 3 weeks later the darn things would fail. We even had some fail on trucks still sitting at the dealership never even delivered yet. Sad when you can't trust a newly manufactured part to make it 50 miles.

I will personally never own a modern diesel. The old ones were pretty darn reliable, the news ones, not so much.

Closing the loop - ended up being a loose connector on the EGR. Dealer corrected the issue and I’m back on the road.

Yo, glad that ya got it resolved. Did you notice any issues with the auto start/stop not working during this time?

No, but I use a TazerJL and have that permanently disabled

OK, error code unknown on my vehicle, but was told a egr code that was the root cause for start/stop issue. Hate that start/stop function, hate it worse that stuff ain't working correctly.
