Looking for help with Car Scanner Pro & DPF data

[kevinjames]

Hello, I’m driving a 2012 JSW. (CJAA)

I’m looking for some insight as to what could be going on with the sensor monitoring dpf soot level with Car Scanner Pro. After a regen, the soot level will go down to the low 20s. A couple days later, soot level will jump from the 30s/40s, to 100, and will stay there until I initiate another regen. It seemed to be reading fine for the last few months. It just started this a couple weeks ago.

Another weird thing is the fan sensor shows 9.6 when the fan is off. When regenerating, it reads 86. Not a big deal, but it makes me think something might else may need to be addressed.

Thanks a lot.

did you figure this out? Having the same problem

Not really.

I ended up upgrading to the OBDLink MX+ adapter to see if it made any difference. It didn't.

I mainly use Car Scanner Pro to monitor the soot level so I know when it's going to regenerate.

I’m having an issue now that just showing 100% soot to regen.
I did a regen with VCDS manually, and soot levels are low but still showing 100% in Car Scanner.

Before I went the Bluetooth route, I purchased the Autophix 7610 to see if I could diagnose why the DPF light was always on. (this was before I took a deep dive into learning everything I could about DPF regeneration)

With this device, there's an option to run a NOx regen, as well as a DPF regen. I ran the DPF regen, and the DPF light still didn't go out. I ran the NOx regen, and the light finally turned off. (I ran these regens while on the highway, maintaining appropriate speed & RPMs)

IF the soot level in the app stays at 100% for a while, even after a regen, I bring out the 7610, and running the NOx regen seems to always bring that percentage down to normal levels after it runs. (usually around 15min while maintaining the RPMs over 2k.

I don't fully understand the whole NOx regen thing, and I can't find any info or video on someone talking about it.

Just my 2 cents.

The car have a NOx storage that requires the insane driving cycle and regen.

That's why those car's DPF crack all the time.
