Hi, I'm a newbie to Nissan X Trail's having picked up my 54 plate X Trail on Wednesday 17th Feb. I've bought a 2.2 dci SVE with 56k miles from Stratstone Landrover, the car is great and I intend in using it and daily driver and as a tow car. However, I have a concern which I would like to know if it's a potential problem or a known trait/character of the car. Upon cold start up the engine seems to me to be very tapperty when idling and under acceleration until the engine has warmed up and then all is fine. Anyone's advice or experience about this will be appreciated.
