2008 Newmar Dutch Star, 8.9L 425 hp Cummings.
Yesterday returning from Morro Bay the high exhaust temp warning came on.
Pulled over could not see or notice anything unusual. Called Paso Robles Truck Center to see if I could get in. Was only able to leave a Voice mail for service Never heard back from them!!!!!!!
So anyway I decided to take it easy and see what happens, I figured it would go into limp mod but never did. When we were almost to Paso about 28 miles the warning went away and never came back for the next 200 miles home.
I'm wondering if it went into regeneration and this caused it.
This coach is relatively new to us. Previous MH had a C-7 Cat. so I'm learning about the 8.9.
If it went into regen won't that be displayed?
