ENGINE AND ENGINE COOLING

 There is a stanless steel exhaust flex pipe under the cab, right side, just after the regen doser that is wrapped in a flex shething.the inside of the pipe cracks and white exhaust flows out and into the cab when the engine goes thru a regen cycle. we had several drivers complain of this issue, upon inspection you can not find any visable cracks in the exhaust. several drivers were having to put the windows down in order to eliminate the fumes inside the cabin while driving. after sending to the dealer, they advised that that pipe was cracked internally behind the sheathing and needed to be replaced. they advised on the procedure to check for this symptom, you have you use the engine software and force a regen session. once you do that , you can see the white fuel smoke and smell raw fuel. this is then drawn up thru the hvac duct and puts it inside the cabin. the repair is a 500.00 pipe plus labor for a total of 800.00. we have 2 of 5 prostar trucks so far that have had to have this pipe replaced, both drivers with same complaint.
