Why is my Nissan X-Trail misfiring?

I've had my 2012 Nissan X-trail 2.0 Dci Tekna for seven months now and am having problems with the engine at 2400rpm. This always happens at some point during a journey, mostly in 2nd gear, with the engine spluttering before eventually powering on.

Nissan have twice reported no fault codes and twice reset engine mappings. The last time I insisted they keep it until it was fixed; again they reset some ECU parameters and initially it was better, though two days later it was back to misfiring. What should I do?

Might be a faulty turbo. Get it independently checked and if they find a fault pay them to provide a report then take that to the Nissan dealer and demand a new turbo.
