In this video, see what to do if the diesel particulate filter on your Vauxhall Astra CDTI Diesel is full, and the warning light on the dashboard reminds you. As our YouTuber advises, to regenerate the filter, the best thing you can do is to keep driving at high revs at a speed of about 60 miles per hour or more, and maintain this for about ten minutes on a motorway, which should turn off the warning light.

Indeed, as we see, the light went off after about eight minutes of driving under the described conditions, maintaining around 3,000 revs at about 70 miles per hour.

The light comes on because the DPF cannot regenerate during short city trips.
