How about higher speeds like km h and more? Is there any activity on the solenoid?
Just to keep you up to date nissan data scan now do an app for android now, to make life a little easier. See the uk forum http www. X trail uk. Co. Uk index. Php
I use obd doctor and it shows km h less than speedo.
Thank you for posting. Use nds ii to check speed at sensor level, gps speed not an exact science!
