Re: DEF Filter Warnings

Remember, the EVIC messages ARE NOT normal. They are final warnings that normal regen isn't occurring or completing and the DPF is close to being full. This isn't normally displayed when operating even though regen cycles are occurring every 70 to 280 miles. The only way to know that proper regen is occurring is by watching exhaust gas temperatures with an ODB2 reader/gauge.

I have discovered I can keep mine in regen mode in town by keeping my revs between 1500 and 2000 and paddle shifting to slowly decelerate. Idling and long stoplights will cause it to abort regen so I try to plan my traffic flow to avoid dead stops if possible. I doubt this would work in LA or NYC.

Re: DEF Filter Warnings

I had a message at 2k miles for this and drove around town for 10 mins and it finished the regen.

What is your Oil Life counter at? I learned from experience that it WILL NOT regen with a 0% oil life, even if the oil was changed but the counter not reset (which is what happened to me a few others).

Outside of that, I can't think of why you should be full in a week...city only driving with a lead-foot off the line might do that, but even then it's hard to swallow.

My JGC refused to go into regen and filled up the DPF. When the dealer checked the codes, there was only oil-life related tripped.

While I cannot know for sure without seeing the programming, multiple users on this site as well as the dealer strongly believe that the system will not regen at 0% oil life. That does not mean there aren't other reasons why the system refuses to regen...

Re: DEF Filter Warnings

Oil quality will affect DPF filter function, as the oil ages, its ability to reduce soot and other 'gunk' slowly declines resulting in increased soot/ash accumulation within the DPF. The concept that the failure of the car to perform REGEN as it is supposed to is related to the oil life indicator is entirely false. It was a myth which resulted from a car review website using incorrect information.

With that said the dealer should ALWAYS be resetting the oil life indicator after services even though they often dont. If they havn't, reset it yourself. There have been plenty of vehicles who have had their oil life indicators reset properly but still having DPF filters filling up to 100% and going into limp mode.

Re: DEF Filter Warnings

I have a 2014 GC Diesel and the particulate filter has now filled up 3 times to enter limp mode each time, with virtually no warning before limp mode occurs. First time, the dealer advised that it was due to delivery at the docks, idling a new vehicle for extended periods, feasible, but unlikely as this first occurred after 18,000km' s of daily freeway driving. Same thing happened 10,000 km' s later, now again at 42,000 km's, 80% all freeway driving. Jeep dealer Tynan feign ignorance, saying it's not a recognised problem. One look at the scores of comments on various forums would counter that. When will Jeep 'fess up and fix the bloody problem!

A dealer putting in the wrong oil can cause this. It's happened to several forum members. Some of the techs at the dealers are just that dumb.

Re: DEF Filter Warnings

I have never had this problem in 32k miles. Yours is not seen that often.
Comment about wrong oil increasing ash content might be valid..

Re: DEF Filter Warnings

Could off road diesel also cause this? What diesel are you using?

Re: DEF Filter Warnings

Just moved to a small town on a island in the PNW. Max speed limit on the island that I've seen is 50 with stoplights and slow ass old people. It takes about 45 minutes to get to some open road. I can't wait to get this issue. Might need to trade the Jeep in soon.

It would cost you less to get the GDE tune that turns off the EGR and makes the burn cleaner with less soot. Regens are between 500 and 800 miles with the GDE tune versus 50 to 200 miles with the stock tune.
