Regeneration nach km | Posts 16+

I made a suggestion to you because there might be something to what you observed.
Unfortunately, you are showing screenshots taken with a different tool of unknown quality. This means you're comparing apples and oranges.
Furthermore, your oil ash content is quite high at 37,000 km for the infrequent regeneration cycles you're experiencing. If I extrapolate based on my mileage, that would be 25.6 grams, which is almost exactly what I get with a vehicle that regenerates much more frequently.
I think we should end this discussion here.

Regarding oil ash:
Your 70 grams were consumed after traveling a calculated distance of 245,000 kilometers.
My 70 grams have been calculated to reach a distance of 253,000 kilometers.


Furthermore, your oil ash content is quite high at 37,000 km for your infrequent regenerations.
This gives rise to several comments.
'How do you conclude that my infrequent regenerations are the norm? This only happens occasionally in my driving profile, and when it does occur, it's usually during long stretches of highway driving.'
2) Your comment contains the statement that the oil ash loading is proportional to the number of regeneration cycles. This statement is FALSE!
3) Furthermore, the calculation model that provides the oil ash loading appears to be very simplistic.
Because for all the vehicles I've checked, the mileage at which the maximum oil ash level is reached always comes out to be 250,000 km.
Specifically, in my vehicle, I've found that the increase in oil ash, relative to the distance traveled, is consistently constant - regardless of whether you have a short-distance and rural driving profile (with regeneration every 400 km) or a more pronounced highway driving profile (with regeneration at 1,000 km, or alternatively, 750 km after using oil type 23R6).
That also makes sense, because the oxidizable soot from combustion is not the main culprit in oil ash either.

Nonsense - and that's the end of it.

Hello,

Guys, you're driving me crazy.

Please don't take it personally.
2. This is my forum, not one run by some app developers. So either abide by the terms of use here, or go somewhere else.
3. This is neither an advertising platform for apps, nor is VCDS suitable for mobile use. HEX-NET has been around for a long time, and it allows you to check what's happening at any time using your phone.
4. The ash in the DPF mainly comes from the additives in the engine oil and is therefore directly dependent on the oil consumption and the type of engine oil used. Fuel consumption or the number of regeneration cycles play a less significant role.
5. 10.2g of ash mass for 37,000 km is a plausible value, see: https://community.dieselschrauber.org/en/viewtopic.php?t=25999

Yes, it is definitely possible, 100%. Whether it is actually active in the respective engine control unit (ECU) is another question.
Furthermore, for a regeneration request, the amount of soot loaded in the DPF is also relevant.

"@TTaurus: If you've had a new DPF installed, it's advisable to reset the ash mass or ash volume because otherwise, the model used by the engine control unit (ECU) for calculating the soot load on the DPF will no longer be accurate."

Best regards, Rainer.
Sure, here's the translation:

"I will remove any personal information and anything that constitutes advertising or defamation from this topic, as it doesn't belong here."
Furthermore, I wonder why "matt" (who is not a customer) has been on this forum for 11 years if it's supposedly such garbage.
A long time ago, you demonstrated that you are not inclined towards constructive discussions, even when you are correct about topics like Russ/Ashes/DPF. Unfortunately, your behavior has not changed in the past 11 years, so I wish you all the best elsewhere.
