2008V10 DPF Force Regen?

As in the title, looking for information on how to force regenerate the DPF's. I cannot find any information on how to do this. In fact, I can't seem to figure out where to read the soot levels in VCDS. I checked out this page https://www.clubtouareg.com/forums/f...en-261282.html but the measuring block values shown on my VCDS do not have any of the information that is supposed to be there. And the code that was listed in the link to start the regen did not work either.

I do not have the Fluid Based Regen System, it is a Fuel Based System

Any ideas on how to go about finding out the soot levels, and how to do a force regen?

The Ross-Tech Link Diesel Particle Filter Emergency Regeneration - Ross-Tech Wiki does not have information for the 5.0 V10, unfortunately...

Why do you want to force a regen?
I had to do this on my Jetta years ago, and it was a PITA.

Well, I don't necessarily want to do a force regen, but I would like to know how to read the soot levels at the very least. And it would be nice to know, just in case I ever need to.

You can read about all the hoops I jumped through with my Jetta here since you don't really have an existing problem that you're trying to deal with....

Diesel Particle Filter Emergency Regeneration - Ross-Tech Wiki
mentions the R5 2.5l motor, isn't your v10 just 2 of them strapped together!



if you haven't already tried the vcds , it may be worth checking the following measured value tags, they are in the engine module , if different you can just flick through all of the MVB and read the descriptions, apologies if you have already thought of and tried this......



MVB 070.1: Regeneration Status (xxxxxxx1 = Normal Regeneration active, xxxxxx1x = Forced Regeneration active)
MVB 070.3: Regeneration Counter/Timer
MVB 075.1: Exhaust Gas Temperature before Turbo Charger
MVB 075.2: Exhaust Gas Temperature before Particle Filter
MVB 075.3: Particle Filter Load
MVB 075.4: Exhaust Gas Temperature after Particle Filter

another avenue is the Ross Tech support, you will need to have a legit Ross Tech dongle that is registered with Ross Tech before they will help, but it may be worth a try if you really need to know how to get in and read the soot value for your engine.



It may not be possible to actually do a burn though the VCDS on your ecu, or it may not be deemed necessary, but the exhaust DPF sensor should still measure a differential pressure across whatever emission equipment comes installed on your model and you should be able to read it.

I prefer MVB 068 where you can read both soot and ash. Be sure to check both ECUís, 1 and 11. Soot load is in % and must be under 50%. Active regens are triggered between 40 and 45%. You can do passive regens by driving at 2200rpm for awhile. 068, 2 is grams of ash and must be less than 150 gms. I have approx 41 gms ash after 120,000 miles, almost all high speed highway driving.
Not sure how to do a forced regen on the V10. Probably wonít be possible if you let soot rise above 50%.

Thanks for all of the replies. I don't need to do a forced regeneration, I just wanted to know if it was possible. But I still cannot see the soot levels when looking at the Measuring Blocks with VCDS in either Engine I or Engine II. Checked numbers 001- 254. Nothing that states soot, or ash or EGT. Makes no sense to me, but very frustrating.
