2017 Audi Q7 — brake fluid is old but still looks clean

Write down what you already tried. A second data point from another 2017 Audi Q7 owner helps more than a generic diagnosis. I'd do that before spending real money. If it doesn't change the out-the-door or the repair estimate, it's noise. This is the version I'd tell a friend.

Don't overfit one forum story to your car. If it still isn't clear on the 2017 Audi Q7, a specialist hour can be cheaper than another round of parts. Then you'll know the next fork. This is from a 2017 Audi Q7 in Brooklyn. No need to make it theatrical. I'm in no rush to be a hero on it.
