Have got the faulty bulb light up but do not have any out, I think,Couple of weeks ago Skoda removed a noise behind dash and thought they might have dislodged a wire. Any way is there a easy way of getting  to the cluster.For instance does the centre box lift out? to get behind dash?.Thanks in advance .

the car uses CAN signals to tell the cluster that a bulb is out

 

Bulb > BCM > CAN > Cluster
