Problem

Hi all. I'm new to this but I need some help. I bought a 2011 2.4 tdci last month. It's been in the garage for the last 2 weeks with a surging problem. The garage have change the injectors and checked everything and said they have reprogrammed the ecu but there is still a slight surge. Any ideas please. Many thanks
