Recently bought X-trail and it has a certain degree of what I can only describe as hesitancy or very slight judder/cough and splutter, always round about 2000rpm, mostly in 2nd gear.

It doesn't happen every time I'm at those revs or in that gear but will always happen sometime during a journey, long or short.

It has been in to my main dealer but "no fault found" when it was plugged in the machine, and as no warning lights come on e.g. DPF regeneration, they were unable to offer much advice other than "it's probably the filter regenerating".

I think the engine management chip could be at fault, my other X-trail (2006) was re-chipped along with many others when new and the fault is similar). I will be taking it back again but would appreciate any thoughts you may have for me to suggest to them so as not to be fobbed off.
