ahhh! make it stop

[desinor at sympatico.ca (Jean-Claude Desinor)]

   You need to remove and open the instrument cluster.
   On the back of the instrument cluster there is a flexible 
printed-circuit-board (pcb). It wraps around, among other things, the 
speedometer.
   Behind that speedo, there is a small solid printed-circuit-board. It 
is the "oil pressure control unit", and that pcb plugs into the flexible 
pcb. In my case, what happened was that the solder of the pins of the 
connector on the control unit had cracked, thus causing the 
light-and-buzz show.
   Having a Bentley will help, pages 70 to 81 on the Electrical System 
section.
   As a temporary measure (and out of frustration) I would bang on the 
cluster (gently!) and it would stop until the next bump in the road 
loosened the connection.
