Well, you're almost certainly going to have to pull the cluster to 
diagnose and fix this.  It might be a bad connection or solder joint 
leading to that section, or perhaps all the bulbs are burnt out (I was 
surprised to see how many there are when I first got my 90Q, about 4 out 
of 12 were good, and it only looked like maybe one was bad)

But it's not too bad to get it out - easier if you remove the steering 
wheel first - but it's only four screws and 3 or 4 connectors which are 
easy to undo - they pop off when you pull the metal clip over them "up".

I did take pictures once when I did this, if they help at all:


The Bentley manual will be useful once you are trying to ID where 
something might be bad, as will a little 12v power supply for testing 
light bulbs.
