Hello, yes I have tried the dpf cleaner, and I ran the Carly dpf option last week on an 4 hour motorway drive and it ran for 30 mins and the soot was 2.0. I have had the car serviced and it’s still doing it, my first thought was the dpf or egr valve, where I live it’s all back windy welsh roads heading to anywhere so it does not really get a good run regularly.
