I made the noob mistake today of letting a couple of people test-drive my S3 without cooling off in between.
Result: boiled fluid.
At least that's what I believe happened. After the session I let the engine run for about 5 min to cool everything down (stationary tho), and when I moved the car the brake pedal went straight to the floor, no braking at all! VAG-COM didn't seem to happy about the situation either...
After a few hours of standing, brakes seemed ok again, except for a little more travel, BUT: now my brake pedal makes a wooshing sound (maybe more of a "pfft") when I step on it. A fellow S3 owner says his does that all the time, so I just thought I'd find out how common this is and whether I should be worried about it?
Second question: What are the warning signs that you're about to lose your brakes to boiled fluid? Kinda scary to just suddenly have no brakes at all!
Third question: Is it safe to drive a few days/weeks with fluid that's been boiled, or does the boiling leave the fluid unsafe? I do intend to replace the fluid asap, but would be nice if I can delay until I make my mind up about brake upgrades etc...
