2016, 150 bhp diesel.

Re-gening on avarage, every two days now.

Had the soot content checked....20%. Never had any warning lights on in 3.5 years, and when I know its doing the business, I tend to drive in the appropriate gear to get the revs up to 2500-3000 rpm for 20 mins to clear it, which it does, and then runs fine for a couple of days before a repeat performance.

Doing my head in, with the usual strange looks as the fans kick in for 10 mins when I finally stop if it hasn't already cleared.

Is this normal?

How often is the car doing only short trips / cold starts, & how far, or doing longer journeys & how far are those trips? ,

Might be a failing dpf pressure sensor or the ash content is very high. Might be worth getting a quick vcds scan to see if there any stored and check ash level at same time. My octavia does the same but only getting short runs these days. When it happens I try and give it a decent long run.
