2014 ram 1500 ecodiesel in cab exhaust smells explained
Channel: mopar ecodiesel
Date: 2015-01-08

This is my attempt to explain the nasty sometimes embarrassing smells in my own ram ecodiesel. 
I own this truck, I bought it brand new, and im in this truck for up to 20 hours per day. I have 60,000 miles of experience with these nasty smells.

If you are plagued by nasty smells, high diesel pee consumption, constant check engine lights, and other emission problems try the following.

First check your air filter, if there is any dirt on it it absolutely MUST be changed. A/F sensor 1/1 is severely sensitive to the slightly dirty air filter, Use only Mopar factory air filter or Fram Severe duty air filter, or Dry flow air filter with foam prefilter.

Second check your fuel filter!!! this filter does not last more than 15,000 miles, it will be severely contaminated and restricted with fine metal particles and flakes of metal at the bottom of plastic container! you can add rare earth magnets in each of the 4 sections to prolong the life of the filter.
You can check the filter for free, you can remove the cup and visually see with out damaging or contaminating the filter any time.

1. fill your def tank 100% full, preferably at flying j truck stop or similar.
 2. go to Walmart and find a fuel additive that has cetane boost. the cetane boost is like octane for diesels. It will make the engine more efficient and help burn the soot and clean out the engine.
 3. triple the recommended dosage and add to fuel tank.
 4. fill fuel tank completely up.
 5. make sure all fluids are topped off in the truck and ready for a long trip.
 6.hook up a 6000lb trailer, really should be enclosed for the frontal mass for wind drag. ( it will create a "load" on the engine ).
 7. make sure all persons riding in vehicle are ready for 3hr trip including snacks, food and entertainment. Make sure kids have gone poop and pee. Make sure wife goes pee even though she says she dosnt have to.
 8. you must find a un interrupted highway that you can maintain a constant speed no less than 55mph for up to 100 miles.
 9. you must find a scanguage or similar obd adapter to monitor C11 output setting for exhaust temperature.
 10. hit the highway, set the cruise at 55mph and enjoy the drive.
 11. watch your scanguage data and watch for temps above 955 f. as soon as the temps start shooting up, ( it may take up to 50 miles ) keep everything steady until temps go back down to 750-900 f (normal towing temps) for an additional 20 miles.
 12. return home and enjoy.

 this procedure is absolutely necessary for all emission system components to reach Lite Off Temp prescribed to ASE standards for diesel emission systems. 
 Per design for all particulate emission equipped vehicles, your exhaust components must be 600c for a certain time depending on how much soot and buildup you have.

 there is absolutely no reason you should not be reaching 28-30 mpg highway empty at 55-60mph.
 I get 17-19 every night towing and city. @ 60,000 miles, and 2000 hrs on my engine and 1/3 idle time.

 To confirm your system is clean, step back to the rear exhaust and you should smell nothing more than pure clean fresh water, when that's the case its at its most efficient
