70 What brake fluid should I use?

A: Check the manual. Most older VWs use DOT 3. The newer ones use DOT 4 or
Super DOT 4 (higher boiling point). Castrol makes one which is both DOT 3
and 4 compatible with a very high boiling point.
The only place I have found Super DOT 4 in the US is at the VW dealer.
One of the dealerships here also recommends Wagner as an aftermarket DOT 4
oil.
The higher the boiling the better: Brake -> heat -> fluid boils -> bubbles
-> loss in brake pressure -> crash.
