Hi,
I have a question about lexus is220d dpf filter regeneration. It is said, that it cleans when running of city on higher speeds.

So, here is a short video of mine lexus is. I was running outside city, at 100 km/h, 4th gear, about 2,3rpm, for 100 km. Almost 70% of the driving time, it was throwing smoke / gas like this: (video below)

Video not superb quality, but at least at the begining of the video, you can see, how much smoke it puts out.. Is it normal??
