I have code 103 on the engine and I just replaced an outlet nox sensor for a check engine light along with a new fuel filter and pressure/temperature sensor on egr for code 124. Is my turbo fubar? My mechanic that I use wants to open and clean my vgr and have cummins re flash it. I need a boost gage. Please help, I feel dumb right now.

First of all, cummins fault code 103 does not exist for that model engine.

Fault code 124 is for intake manifold pressure.

I am thinking you have the wrong codes, or some other info missing in your post there.

and what is a "vgr" .. was that a typo?
