2008 Volkswagen Beetle Q&A
2008 Volkswagen Beetle Question: The dealer has recommended a brake fluid change at 20,000 miles.
You can but, it really isn't neccessary. Just check the color of the fluid every now and then. When it changes to dark brown in color then replace it. It starts as a light yellow to clear in color. - csubak30
it could need it only if there is moisture in brake fluid or was contaminated with something else, or is very dark - globalhelper
