Paccar for owner operators?

I have very little experience with the MX13 just git a 2019. Ive heard mechanic say the def Quality sensor was a bug problem with the def system on paccards.

 

No I found it while checking continuity and reference voltage to the sensors. Kept getting sensor faults but sensors were testing good. Checked harness and found high resistance and some light corrosion
Took out the emission control ecm.

 

Red flashing light in DEF gauge means there is a fault with the SCR system, solid red would be low DEF level. Need to get hooked up and get the P codes. EPA 10 rely heavily on EGR and regens more, so air management cleanings and EGR cooler cleaning is regular PM.

 

How much did flushing the egg cost you?

 

If you’re asking me about the egr cooler flush
I get it done every year
Just did it again a few weeks ago. I don’t have the actual receipt but the estimate was around $900 but I think they flushed the entire system. Not sure if that’s a regular thing or not
Pretty sure Ogden was $4-500 around 2018
So either I had more done. Prices when up or?
