Brake Light comeing on when starting out

[B5A42.8L]

i have a question and i feel stupid asking this. I have a Audi a4 1999 2.8L manual and a lot of the time when I start out in 1st gear and start faster than usual (or for some reason that i dont no) the brake light comes on blinking and makes a beeping sound. I was just wondering what this is. Please dont tell me to look at my manual because i dont have one and dont wonna go get one.
Thanks for all the help

Wheel speed sensor maybe? My front left Wheel speed sensor is faulty and the same thing happens. Check your codes to be sure.

Is your brake fluid low? Is the ABS light coming on also?

no the ABS isnt on its not all the time also

What's not on all the time..... the brake indicator? Is the fluid low? The reason I ask this is because as you take off , stop, or turn the brake fluid sloshes around causing the level to change. If it is the indicator light that says brake in it (in red) it is most likely a low fluid level.
