 NOT the thermostat as guage would show SOMETHING. Either you replaced the
wrong temp sender (guage vs ECU) or the guage is bad. I don't have the
manual for this car but the senders can be voltage/resistance tested at cold
and running temps to determine if they are working.


OK, I have a coolant temperature gauge issue.  Car is a 98 A4 with a 2.8 30
valve.  The temperature gauge is buried at cold, however in stop/go it will
move up eventually to normal.  This past summer (first one with the car), it
went to normal and no overheating.  I get heat without a problem.  Sender
was replaced, could it be the thermostat?  How difficult?
