If it's diesel it'll probably be doing a dpf regeneration. Is it used only for short journeys?

Yea I'd say it's the car trying to do a dpf regeneration. My advice would be to take it on a motorway run for 20 mins- half an hour.

Cheers for the advice

You're welcome. You could always try adding dpf/egr cleaning additives when you refuel to see if that helps 🙂
