What type of brake fluid should be used in an Audi 80?

I'm planning to change the brake fluid on my Audi 80 and I'm wondering what type of brake fluid would be recommended for this specific model.

For an Audi 80, it is recommended to use DOT 4 brake fluid. This type of fluid has a higher boiling point and is suitable for high-performance vehicles.

As an Audi mechanic, I have to say that DOT 4 brake fluid is the way to go for your Audi 80. Just make sure to flush and replace the fluid every 2-3 years.

Personally, I've been using DOT 5.1 brake fluid in my Audi 80 and haven't had any issues. It's important to stick with either DOT 4 or 5.1 and not mix them.
