Hi. I have a 2012 Peterbilt 386 and the def has been deleted. The ECU went out and needs to be replaced, but the dealership is refusing to work on it because the def has been deleted. Is there a way that I can get the new ECU put in the truck, and programmed, but keep the def deleted? I am assuming since I bought this truck used and the def was deleted which is common on this model, that it is just going to cause more issues in the future if I have the emissions system reintegrated. I would appreciate some help with solutions if available. Thanks so much!
