    Subaru Forester 2015: Diesel particulate light flashing

    Subaru Subaru Advice Subaru Forester Subaru Forester Advice Subaru Forester 2015

    Eight weeks ago I purchased a 2015 Subaru Forester diesel from a dealer. Today the diesel particulate light on the dash started flashing. Two local mechanics said it was a big job, $2000-$4000. It has done 40,000 km, is this a warranty issue? What should I do?

    To start you need to have the filter cleaned out by what it called a manual regeneration. It’s not a warranty issue. Take it to a Subaru dealer and get a quote from them. The reason the light has come on is that the car hasn’t been driven in a way that ensures the regeneration takes place automatically. It could be because of the way you drive it, or the way previous owners have driven it. When you talk to the Subaru dealer about regenerating the filter also ask about the way to drive it so the regeneration happens automatically.
