Question about 1991 Audi 90
Bad relay to fans usually causes this and if computer is shutting it down over heating issues then means it's reading correctly from the coolant temperature switch meaning that's working. Given that the computer wants to shut it down and knows it's hot should mean it's sending the signal for the fans but no results because relay. Easier to determine if you have twin fans because if the fan motor was bad only one would not work.
