Hello, we have been driving a Mazda 6 Kombi diesel with 121 hp for 2 years. However, we are in the workshop every 6 months, as the DPF control lamp lights up continuously and we always lose power. We were told that it is because we would only drive short distances and thus the filter cannot generate itself. Also a letter to Mazda in Leverkusen did nothing, on the contrary, we were too stupid to deal with the car. In mid-May we had to go back to the workshop and The oil had to be changed again, we were allowed to cover costs. After 2,500 kilometers he is now again in the workshop, this time already for 1 week, as still tests have to be carried out. This was only a short excerpt from our problem. We are looking for other owners who have this problem, because we do not like that of Mazda any more. Please for a short return information, if you also get so. Thank you in advance. MfG JHMSW
