Manufacturers have not thought of this problem??? For ambulances, fire trucks on the way to a fire going to limp mode?? You are kidding right?
I guess their only answer is follow some regular high idle procedure or something that requires extra time, cost, and man hours.
Things like this coupled by improvements to gas engines like direct injection etc, will just hasten the demise of the diesel engine we use.
In my fire service career, I operated both gasoline and diesel powered apparatus. Granted, the diesels didn't have emissions equipment that is now required, but they hands down outperformed gasoline engines. Getting to an incident was the easy part for either engine type. Pumping water at a fire scene for an extended period of time is where the gas engines fell flat.....mostly overheating problems despite having the ability to circulate water from the fire pump through a heat exchanger in the radiator to try and keep the coolant temp down. The larger V8 (Ford mostly) engines and large displacement 6 cylinder engines made for fire apparatus by Waukesha & Continental also were real bad about carbon accumulation. Guess that comes from the cold starts, prolonged idles, and short run times.........
