I am familiar with instrument cluster problems having already replaced one however I have a new problem that I am not sure if it is the cluster or not and have not been able to find an answer within the forums.
Whilst driving I experience intermittent total instrument power failure simultaneously with loss of display on the climate control and the steering wheel control illumination, this lasts from a few seconds up to a few minutes. the instruments lose all the dials digital screen and illumination and I also appear to lose the indicators although this may be just because the repeater on the dash and the audible click has also stopped working.
This seems more like a power supply/canbus? problem.
I do not want to replace the instrument cluster again if the problem actually lies elsewhere. Does anyone have any experience of this issue or suggestions on how to diagnose without getting a garage to start replacing parts one by one.
I have also replaced the battery within the last 12 months.
