No can do anymore. There is a quality sensor that detects the amount of water/urea in the tank. If that's off, error code and limp home mode is soon after. This is a US requirement, I don't know if other countries have this sensor or not.
Maybe there's a way to trick the sensor, like putting a hot water bottle on the cab temp sensor so the truck can be idled
