“04 Thomas Saf-t-liner HDX EGR issues
I have a 2004 37’ Thomas Saf-t-liner hdx, Mercedes 2003 OM906LA engine and I believe an Allison 2000 I’ll need to go back and check. Been reading up on it and I’ve seen around this era buses with EGR issues being a big drawback and I’m trying to figure out if I’ve escaped that with the engine being an “03, as I’ve heard “04 buses and after is a no go. I’ve seen people mention disconnecting the EGR as well. How difficult is that process, and how does that work?
Also have been trying to figure out if I’ve also managed to escape the computer controlled systems, if it is an Allison 2000 I think that is computer related, but there was a short time period where engines could be mechanical simultaneously?
Ultimately trying to figure out if I’ve made a mistake with this purchase, does anybody have any knowledge about how these buses are. Appreciate any knowledge on any of these questions
