Yes is will have DPF. It would need one for EU4, never mind EU5. Avoid repeated short runs from cold starts. Be aware that the DPF will actively regenerate every 250 miles or so and this will probably happen while you are on the motorway. Use only the best diesel. Check the engine oil regularly for a rise in level. If this happens get it to a dealer. But DPFs have not been generally troublesome on Sportage diesels.
