Hello, since also younger used beziners (diesel already for a long time) have to be equipped with a particle filter, I ask myself the question to what extent the OPF can cause similar problems, as they say to the DPF. I have been driving a diesel (see signature) without DPF since 2008 and can therefore not agree with the problems with the particle filter. So far I also thought that at least my current driving profile – Mo-Fr every day 100 km – will continue to be the diesel Is this really the case? And: what does this look like with the petrol engine with OPF? Guess that the free-burning process also takes place off the highway without any problems. Is that correct? Greetings
