Hello, have a 2009 diesel and drive 85% motorway. At approx. 250km he has first glowed through the filter. I already feared the worst because the consumption was 100% higher. Recently at 15000km it was time again (and certainly also sometimes in between). I am on the highway and the consumption rises from approx. 4l at 120km/h to 7-8l and the over determined 50km distance. Today early, 700km later already again. Duration again about 50km. In between the box had 10 hours s even in the thrust phase, where the consumption indicator usually goes to 0.0l, it remains on 1.1 l. Cut in the bucket. Does anyone know how often this cycle is used? I mean, I’m practically always on the track. Is this somehow measured or how is it controlled? That costs a fortune 😉 Greeting Martin
