Hello, yesterday I read an interesting article in the AutoMotorSport-edition. The 2.0T gets away with the test number of particles. Almost full score and this with the model year 2018 without OPF. If you read the article like this then the dust emission is really low even without the OPF (model year 2019). I am happy with my model year 2018 and do not have the risk that the filter causes trouble. Articles I have just attached. Have a nice weekend!
