[s-cars] Check system

(Brief reminder: urS6 with dead autocheck system display)

Thanks for the suggestion, Stott.  Shoulda thunka that 
myself.  Duh.  :-(  OK.  Swapped the instrument clusters 
today.  Pulled both and stuck the old one in the new(er) car.  It 
worked as designed.  The check system display functioned as did the 
radio station display.  Then when I fired the engine up I got a beep 
and the icon saying the brake wear sensor has worn through came on 
with its accompanying "beep".

The "beep" has been there all the time but the display has been 
dark.  (And is again since I put the instrument clusters back where 
they belong.)  If I can get the display working I can deal with the 
wear sensor signal.  BIRA system 3 brakes are on the car and the 
sensor  leads can be shorted out easily enough.  I suspect that a PO 
simply got tired of the wear sensor icon and decided to "fix" the problem.

OK, the fault is located in the new IC and is not some other piece 
elsewhere which has been pulled ot cut or...  Close visual 
side-by-side examination of both ICs with the back off both ICs 
showed no readily apparent differences such as a cut wire or a cut 
trace on a board or whatever.  Bentley, on the check system, assumes 
that the display functions and that any problems will be associated 
with the "other end" of the system - the sensors it reports on.

Has anyone repaired or replaced the display unit?  Does anyone have a 
nice IC for sale with ~87K miles on it?  Or how easily can the 
cluster mileage be reset to that of the car?  Probably illegal, huh?  :-(
