Audi coolant is said to be “Lifetime” and if I remember correctly it say not to change it…same with the transmission fluid (manual or auto). Usually during a timing belt service procedure, rather then reusing the coolant people will change it although not necessary. It’s just harder to collect it cleanly enough to reuse it.
