Hi Folks,
The above fault occurs when there is a poor earth.
Even when cleaning all the earth points the problem was still slighty evident.
The cure was to install another earth lead from the off side rear cluster to an existing earth point.
Photo below shows how i did it, and the problem was cured.
This fault is an MOT failure..
