My old 1983 Audi 100 didnt have a temp gauge it had an overheat warning on the driver information system(only displayed if the car overheated). Although everytime you started it it went through a self check to make sure the sensors were working properly, it even checked the side and brake lights. I thought it was pretty high tech for a car so old ![Big Grin :D :D](/styles/default/xenforo/vbSmilies/Normal/biggrin.gif)
