The temp sensor that feeds the CIS computer is in fact on the bottom of the 
coolant outlet flange.  It is part number 035 919 369M.  It should have 
black/red wire and a brown/red wire.

The dash gauge and flashing overtemp light are fed by the sensor on the top 
of the flange.  It is part number 049 919 501B.  It should have a 
blue/yellow wire and a blue/brown wire.  The blue/yellow wire also goes to 
the coolant resevoir level sensor.   The coolant overtemp or level sensor 
can both cause the coolant light to flash.  The blue/brown wire is variable 
resistance to drive the temp gauge.

Hope this helps.
