Def system delete

Has anyone deleted the Def system? We have a 2016 Integra Anthum with a ISL9 Cummins motor? We have had the warning signals come on and have been afraid to drive it since. We saw where the DEF Platnium May be the fix.

I don’t think def platinum will do anything different than regular def except to take more of your money. They both have to meet iso 22241 standards.

The marketing for Platinum stresses the reduction of “deposits” in the exhaust/scr system with its proprietary additive. Does it help? Who knows. However, the major issue with DEF has been with the tank and sensor head, not issues downstream at the injector or catalyst chamber, though they do develop.

To the OP, we don’t know which signal came on for your rig, so we can’t advise about what you need to do, or if you need to be “afraid.” A 2016 may not even have the problematic DEF head if the engine is one or more years older than the coach.

Correct. Because of the timing of Entegra's model year changeovers, it's highly probable that a 2016 Anthem would have been built in calendar years 2015. And its chassis would of course have been built before the motorhome.

The major DEF issues started with revised DEF head unit sensors installed on chassis products built after 1/1/2016. So while you may have fault codes related to your DEF system, you probably don't have the potentially disabling issues that are the subject of most of the discussions here on iRV2.

If you have a Cummins service center nearby, they should be able to connect a diagnostic code reader to your coach and let you know if you have anything to worry about or not.

Good luck and keep us posted on what you learn.

DEF is DEF by law. It must be 32.5% aqueous Urea and 67.5% deionized water by mass. There are 2 independent aftertreatments. The first is called the DPF or Diesel Particulate Filter. It is a big ceramic filter inline with the exhaust that captures soot & other particulate matter and keeps it from going into the air. As soot builds up in the filter a system (completely different from the DEF sensor system) monitors the exhaust flow through to filter. When it gets obstructed to a certain amount a regereration is triggered and the filter is heated up to about 1,000 degrees F for a period to burn off the soot. It is pretty much like the “self-clean cycle” on your kitchen oven.
The DEF fluid is part of the SCR or Selective Catalylic Reduction. This system injects the DEF fluid as a fine mist into the exhaust in front of a catalytic reaction chamber. The urea in the DEF is broken down by the exhaust heat into ammonia and the resulting ammonia reacts with Nitrous Oxides in the exhaust stream and breaks them down into Nitrogen and water thus keeping them out of the atmosphere. A modern Diesel engine outputs cleaner air than it took in. In certain situations they literally clean the environment as they go down the road.
The DEF systems that are failing are just monitors for DEF level in the tank plus purity of the DEF fluid (so you can’t just add water) and the fluid temperature. The failed sensors have nothing to do directly with the actual emissions control. Unfortunately the EPA doesn’t trust owners to always keep the tank supplied with real DEF and not just water-and no, you can’t just pee in the tank. It’s Urea not urine.

Since exhaust coming out is cleaner than air going in kinda makes you wonder what the big push for electric is all about.$$$$

It’s all about control. With petroleum based fuels available from many many sources and electricity only available from a Public Utility, if you were wanting to control movement which energy would you want people to require.

Note that nitrous oxide emmisions have nothing to do with cleanliness. Nitrous oxide is a naturally occurring substance, being created by bacteria in soil and in the oceans, and by lightning strikes in the atmosphere. It is a vital fertilizer required for plant growth. The tiny amounts entering the atmosphere during the combustion process are insignificant. If anything they are a positive contributor to life on earth.

I do know someone that did it on a 2015 anthem but he would never talk about it on the forum. They took al the emissions and def tank off his coach then reprogrammed the ECM. He never plans on selling the coach so for him he feels he is better off

I believe he said it cost around 5 to $6000

I know someone who had it done on a pickup truck. Same price about 5-6k. He claimed it got him about 60 extra horsepower.

Thank you for reply’s. I forgot to add that in Seattle area there is a Def shortage. We could not find any Def. I ordered both the regular Def and Platium on Amazon. After reading the truckers blogs I guess it is widespread. Stores are saying that Covid causes the slowdown in manufacturing. We drained all the old Def out before we went shopping. We did sit our coach last year due to Covid and read where the old Def could be a problem. Now we will sit some more. Note to self: don’t drain old before new in hand. Also our Cummins ISL9 motor was mfg in 2015 and Anthum is a 2016. Since we had all the warnings go on when we started we parked it again so we wouldn’t get stuck. Good idea to have Cummins do diagnostic check. Thank you.

I did a deleted the DEF on a F350 and it worked great. I then put it all back on before I sold the truck.

I just got 4 jugs of DEF delivered from Walmart, 2 day free delivery and a good price. I’m in Florida so maybe different than delivery time in Seattle but you should check.

Now what a terrible thing to say about our wonderful government that thinks only about protecting us from that nasty oil. Let the govt take care of us and everything will be wonderful.
Terry hit the nail on the head but the sheeple continue to just get in line. Wear your masks and drink the Koolaid. Well, maybe the masks are not such a bad idea just to make the yet-to-be-infected feel a little safer.
