Practical experience with particle filters 2.2 DTI

Hello, I have just searched for threads on this topic with the search function, but found nothing really up to date. Maybe it’s because the filters are only available now. I have the following problem: For the upcoming TÜV I would have to exchange the oxicate with my 2.2 DTI, since it is now in a state of total resolution. As I have read, the other has probably already done so. Of course, it’s close to the oxicate. This is also much cheaper than a new oxicate because of the 330€ control clearance. Now I read on the HJS page that there are different variants of particle filters. Does the particle filter replace the oxicate with the 2.2 DTI or is it additionally installed ? (the latter would be quite stupid for me of course) Does anyone already have this with the 2.2 DTI and how are first practical experiences? Performance, consumption etc.? Greeting tungsten
