Dpf cancellation and black smoke

Recently I bought a 2011 model 308. The first time I took the car, it gave dpf error. I told the friend I would buy it. He cleaned the DPF and canceled it. The car did not smoke when I first went and black smoke was the last time I went. Still, that problem continues. What is wrong with this situation? Also, will the car to be examined cause problems in the inspection next week? Thank you to everyone & nbsp;

I wonder if anyone knows

I normally know that they are canceling DPF on vehicles with performance software thrown out (to make black smoke go & nbsp; ) particle filter may need to be replaced. About this issue, we have more experienced & nbsp; friends, masters in the forum, I think it will be healthier if they give a hand to the subject. & nbsp; However, it may cause emission problems during the inspection. I wondered if you had an examination or not. Get well soon

While dpf is being canceled, bs of the vehicle should be closed or it will give an error continuously. The black smoke event can have many causes. catalyst - injectors etc. there may be problems with inspection. emission values may be high.
