Regen frequency.

[john7080]

Hi everyone,
I've just had a replacement DPF fitted on my 2020 TGE and as such I've become paranoid!! Roughly how often would you expect an active regen to take place? Fairly short journeys currently

Thanks in advance

My conversion isn't ready yet so ive not owned one so far but how do you know when the regen is taking place .

Only indicator is the revs increase slightly at idle. If you look on the T6 forum someone is making a display that woks with a obd dongle and tells you the actual status otherwise the only way of knowing when the cycle has finished is to keep looking at the idle speed

the VAG DPF program on the Google play store will work with an OBD2 dongle if you have an android head unit, i use it, it will play a notification noise over the top of my music when regen starts.

Thats a great bit of information I guess you have to have the obd reader permanently plugged in and connected though .

Can you point towards the app that you use in the appstore?
I have a permanently mounted obd dongle and with an app like Tasker I could probably get the dpf app to start automatically on my phone.

Found, tested the free version and found when using group 97 'experimental' my engine code DMZB is readable. Then bought the full version.

On the picture the temps are low due to recently starting the engine.

Cool app!

that's the one, really interesting seeing when it does a passive regen (basically when the temps get high enough via normal driving)

Passive regen doesn't seem to do much except slow down the creation of soot a bit, it still increases on mine, the active regen burns it off.

Yup, I'm really interested in regen as I use HVO100 as fuel and it seems to start the regen but hardly injects ureum into the dpf. My ureum use:

See pictures.

The display in the vehicle stays on a 30.000km range for a long time, it used to be 32.500 for thousands of kilometers.

The reason I use HVO100 is too keep the engine clean, I've taken apart my previous TDi engines and have had to clear away so much muck because of the EGR it's just ridiculous.

I don't want to remove the EGR nor disable the AdBlue system.

My OBDlink LX is permanently plugged in at I use it a lot to see alternator voltage, turbo pressure and air intake temps etc
