2023 Audi S5 — brake fluid is old but still looks clean

Fluid looks clear in the reservoir but has been in the car for several years. Would you change based on time/moisture rather than appearance? I am in Nashville. If I figure it out I will update the thread.

I'd keep this practical. Verify the cheap/easy branch on the 2023 Audi S5 before a big repair or a big spend. Then you'll know the next fork. No need to make it theatrical. Worth doing even if the car feels fine right now. This is me being the wet blanket on purpose.
