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? ,
