Thanks for your reply. I will have a look.There have been issues in the past with errant displays on the instrument cluster and the most common cause has been the earth to the stereo unit. It's easy to check.
The ECU must be getting the input for the engine speed or you'd have trouble driving it ...
Failing the stereo earth, it could just be a loose/poor connection on the back of the instrument cluster (has happened before).
