2021 Audi A6 — brake fluid is old but still looks clean

ShopHunterCommunity StarterDec 31, 20252021 Audi A6 PrestigeSan Antonio
2021 Audi A6 Prestige, about 98,500 miles. 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 San Antonio.

I'd keep this practical. Verify the cheap/easy branch on the 2021 Audi A6 before a big repair or a big spend. That's where I'd start. Stop there until you know. Worth doing even if the car feels fine right now. This is me being the wet blanket on purpose.
