Lets get dunks question out of the way.
Changing Brake fluid is often on the service schedule of many cars. Every three years is the usual interval.
Why? Brake fluid is supposed to be hygroscopic, ie absorb water. The old lags say this is bad because your brake fluid will boil, your brakes will fail, and you will crash into a truck at the bottom of porlock hill. The new lags say this is bad because the water in the fluid will rust your abs pump, seize your wheel cylinders and you will crash into a truck at the bottom of porlock hill.
Its all rollo of course, I have never changed brake fluid and traveled porlock hill safely many times.
Having said that, I will get mine done in the Beemer, because the car will bleat at me to get it done.
We now return to your normal programming, "Why is main dealer servicing so s***"
