The following problem: The workshop wants the DPF to be changed, which should do far more than 1000€ in total. Now I have researched something and found out that cleaning the DPF should be enough for the time being or could save costs. The question only arises to me, how to get to this DPF and how to clean it best and what to take into account. I am very grateful about helpful answers. With fre Greetings and many thanks to all Yannick
