Hello I didn't find the answer to my question in the previous posts, if I made a mistake, I apologize. RRS 2018 4.4 V8 there is a problem... the car drives very short routes and the DPF cannot be cleaned :/ this results in an increase in the engine oil level and the need to replace it on average once every two months the best way is to drive the RRS on the route to get rid of it it's hard, it seems. RRS does not show momentary combustion, which means it is difficult to determine when the DPF is working, I heard somewhere that you can connect an LED that will light up when the DPF burns out. I'll tell you more... apparently one pin in the OBD gives such a signal during firing... can anyone confirm or give me tips on where to connect such an LED? I'm happy to cheer up my friends
