And the beat goes on. This almost seems inevitable, thanks EPA!

The EPA is not at fault for the pandemic cause of supply problems, which can and is affecting other parts and components as well.

A possible work-around solution:
Def Sensor Simulator

Yep, but like the Def sensors themselves, I tried ordering the parts needed this morning and all are out of stock and back ordered for about 6 weeks. I thought that may happen.

If it occurs with us hopefully the programming fix to stop the derating is approved

 

[Ken & Sheila]

EPA has approved letting the manufacturer's change the software to avoid the derate at least remporarily. Waiting for Freightliner to come up with the change. I'm sure the actual software change will have to be OK'd by EPA.
