Hello, in spite of the problem often discussed here I still have some questions. I have driven a lot of short distance lately and have interrupted 2x a regeneration. Shortly afterwards the DPF lamp came (permeable) and since then the suit has considerably decreased. But this is not a real emergency run, because I had already experienced such a thing before. With enough start-up it runs on the straight still 130km/h, only on climbs it slows down. I have tried several times on longer motorway rides (30 – 60km) to burn out, unfortunately in vain. I yesterday dropped a can of Liqui Moly DPF additional and filled it up. I have the opinion since then it runs a tick better, but lamp still burns. Oh yes, an oil thinning does not yet take place or has not yet found place. My questions are: Can I trigger the regeneration again by long rides? If yes, is it better to give “spule” and generate heat or rather to roll there constantly with 90km/h? Or is it better to let the car stand completely?
