I have a 2010 VW Jetta limited that was throwing a brake light and beep sound every few days, then became daily. I have an extended warranty but was told at an oil change (tire discounters) that's the fluid or sensor could be the problem. Merrit was awesome at DJ VW, he told me to pull in, 10 minutes before they opened and checked brakes, fluid and pedal. In less than 10 minutes he had my brake fluid topped off, the light and beeping gone and didn't even charge me for the top off! Thanks Don Jacobs VW service department.
