G350d – frequent regeneration despite low DPF loading

Hello dear G-Meinde, last week I had my G350d in the workshop because it has been constantly regenerated for some time (100-200km, every 2-3days, despite regular cross-country trips) – The regeneration is clearly recognizable by the changed exhaust noise background, when parking it “smells” hot and you can feel the accumulated heat from the underbody – The analysis of the data however revealed a last stored regeneration before 800km and a current loading of 30% – after i h my vehicle had picked it up then it didn’t take 100km until a regeneration was started again – can’t it be that the load rises so fast – Does anyone have an idea what it might be about? Are only completely completed regenerations stored? Besides, I have the feeling that the exhaust line to DPF incl. SCR Kat gets much hotter than before. Thank you and greetings, Lars
