Is this a normal DPF Soot Build?

[Geos7812]

We just got our 3.0 and have 200 miles on the odometer. I put the scan gauge on at 100 miles and immediately it had a Regen. I figured the Jeep may have idled as it was working it’s way to the train etc. However, we are just over 200 miles and we have a soot load of 72. The last 100 miles have been 100% city but isn’t that really quick to fill a DPF? What is everyone’s else experience?

thank you,

My jeep is still a baby on miles so my experience might be coincidently. I’ve been doing a lot more daily driving recently and with the cold weather I let it idle to warm up while I get the kids in it, etc. Prior to recent couple weeks I never had a regen and it was sitting between 55-70% for a couple thousand miles (fluctuating in that range). prior to recently, I mostly did dynamic driving loads and highway like driving so very little stop and idle.

Earlier this week I had my first regen while warming up in the morning and after a couple hundred miles of traffic and lots of slow speeds and idling (low load level) I’m up to 70% already. This recent quick ramp up makes me think it is quite possible to have a regen in under 1000miles. The last couple weeks have had me sitting in traffic, lots of traffic lights and the morning warm ups which is a new driving situation for the jeep. If that is your driving profile and I’m right about my assumptions it seems normal to me.

Now I don’t know, but I’m starting to think idling really ramps up the frequency of regens. I look forward to seeing if my assumptions are correct and long run times, with minimal stops and engine loaded burns off the s reducing frequency of regens.

I don’t know much about modern diesels so if I’m wrong I hope someone corrects me.

thanks. We have very minimal idle time but you are right that idling is horrible for DPF.

Thinking that If may be normal. Put 200 miles of mountain driving this weekend. Had very little spot build due to passive Regen. Looks like I will have to drive the Jeep on weekends to “blow it out” after my wife rips it around town during the week. Ah shucks! What a beast in the mountains. 2000 rpm up any hill I pointed it at. Loving it.

Don’t overthink it and simply let the emissions system take care of itself and do it’s thing.....

hah! Solid advice but oh so hard to actual do it.

Toss Scan Gauge......

Problem solved.

Seems right. I’m averaging 300 per regen, over 7k miles… that includes six rides from Pittsburgh to Buffalo, and one from Pittsburgh to Atlanta. Usually about 200 when it’s just city driving, but has been as low as 160 or so.

Gotcha. One Regen every week to 10 days. Makes sense.

Is Scan Gauge a brand name? Works off your phone or its own little screen?

These are the two most talked about gauges in this section.

I installed the scanguage at 25k miles. I was surprised at how often I was in regen. Stopped stressing about it and realized the biggest benefit of the scanguage is knowing I am currently in regen don’t shut it down. Before the scanguage I think I was doing a lot of partial regen. I have seen the dpf spike and drop in increments that I did not expect. I do enjoy at least knowing what’s happening via the scanguage
