I'm trying to get my recently acquired Polo on the road with a new MOT. Things are going well but most of the time I have no instrument display, including speedometer and fuel gauge. I did get a few minutes of display showing me the car has only covered 16,700 miles and has 3/4 tank of fuel! I took the cluster out and gave it a session of electrical contact spray but no results. Any info out there?

Hello! Do you have access to the wiring diagram for the car? It's peculiar that none of the dash works. What type of instrument cluster is it? What year is the car??
