1 & 4 are SCR, 2 & 3 are very likely JBD.
I do not think any of them trigger limp mode.

How did the dealer visit go?
I have the metering valve actuation error along with some reducing agent pressure problems. Did they replace your DEF pump?

They didn't see the codes because I had cleared them. I figured if they came back, I'd bring it in, and didn't want to cause any disturbance during my free maintenance goodwill since I was three weeks past my original warranty expiration. My CPO warranty will cover any emissions related items and waive the deductible. |
