Steve Q Posted September 5, 2021 Share Posted September 5, 2021 If it's diesel it'll probably be doing a dpf regeneration. Is it used only for short journeys? Quote Link to comment Share on other sites More sharing options...

My advice would be to take it on a motorway run for 20 mins- half an hour. Quote Link to comment Share on other sites More sharing options...
