No, you shouldn't do that. The system is designed in such a way that it can burn off the produced gas. Since this gas ignites at a certain temperature and oxygen concentration, everything should be fine. However, if your substance accelerates this process, it could lead to excessively high temperatures locally, causing the material to sinter together.

If you still have the DPF: Use an endoscope on the inlet side, or use a flexible tool to open it up. I bet you'll find completely blocked channels.

Generally speaking: To all those who read this: Only the fuel specified for a particular vehicle should be put in its tank. When it comes to engine oil, you should also adhere to the standards and can choose between low viscosity (LL) and "normal" grades according to your preference.

If you don't exclusively drive short or very short distances...

Specifically: Because your issue is unusual in this context, this additional information is certainly a reason for concern. However, there might be another underlying cause (e.g., excessive oil consumption due to a faulty component, a defective fuel injector...). Investigate the matter further; otherwise, you'll likely find yourself back in the same situation soon.
The Russmass value being below 0 is likely due to the loading factor you specified being too low (1). Is this a DPF from "eBay"? They always seem to have only been driven for 4,000 km, which seems rather suspicious.
"Especially with all-wheel drive vehicles that have a transversely mounted engine, any work between the turbocharger and the exhaust system is simply awkward. Therefore, find all the underlying causes, otherwise you'll be doing this again soon."

Thank you for your assessment; there might be something to it. The engine hasn't been consuming excessive amounts of oil, and the injectors are still within normal parameters according to the test results.
ich werde das weiter beobachten und berichten wenn es was Neues gibt. Leider find ich beim VCDS nicht die Funktion zum anlernen der Differenzdruckgeber, da bin ich scheinbar zu blöd.

Best regards, Jens.
