    I have a 2007 Ram 3500 with the cummins 6.7 L 6 speed Manual transmission and have a factory engine exhaust brake system. I have had the truck into the dealer several times for the same problem steaming around the ehaust brake system. This last time in the dealer they informed me that I am supposed to leave the switch for the exhaust brake system on all the time during idling, and while driving even in city or highway travels even if not pulling a trailer, Has anyone else had troubles like this

    I have the 6spd AT , but I was told by the dealer's service tech that I should turn the brake on when warming the truck up in cold weather, and I should also turn it on frequently when doing short commutes. The tech also said this saves the turbo from carboning up and extends the life of the turbo.
