The abs system uses sensors to detect the rotation speeds of the wheels. They "count" serrated notches on the driveshaft cv joins which are located in the centre of each wheel on the inner side. These serrations can become clogged with grease/ rust/road muck so the sensors read incorrectly causing the fault light to come on. I can't remember whether it's possible to clean the serrations out without pulling the driveshafts out (quite a hefty job as there is a large and very tight nut on the end of each driveshaft which has to be removed). You'll need to have the car jacked up and on axle stands or better, up on an inspection ramp, then from underneath, scrape out all the gunk from the serrations with a small screwdriver or knife blade whilst rotating the wheel to gain access.
The sensors themselves can also develop faults, often caused by wiring breakage especially on the front wheels. The wiring to the sensors become brittle with age and can fracture-moreso the front ones as they are subject to most strees due to steering movements of the front wheels. The distance between the sensor tips and the cv joint serrations is also quite critical too.
In short: First ensure the brake fluid reservoir is topped up with the correct brake fluid (for abs systems), then make sure the power steering fluid reservoir is correctly topped up with the correct(usually mineral based) power steering fluid. Deficiency in either of these reservoirs will cause the abs warning light to come on and is by far the easiest thing to remedy but do make sure you use the correct fluids-if in doubt, consult Audi. Next check the wiring to the sensors, inspect the tips for cleanliness and positioning , then have a go at cleaning the cv joint serrations.
If these remedies don't solve the problem, it could be the bake servo (on the end of the brake master cylinder in the engine bay) or at worst (most expensive) the abs pump itself, although these are,thankfully, very reliable units.
Hope this helps, feel free to contact me for any other help I can offer.Good luck, Bob.

abs stuck on key on and running full time right?
so check brakes for damage or worn out.
brake fluid level not falling? look yet? look when checking oil every time.
abs can not work on cars with bad brakes, (its not god like)

Abslight stays on no brake lights

Fuse 12 (10 Amps) may be burned out. Its located in "Junction Block". Losing
fuse 12 would kill the ABS systems and light the ABS dashboard light.

Fuse 11 (20 Amps) may be out. Its located in "Power Distribution Center". Losing fuse 11
would kill the brake lights, and light the ABS dashboard light. If fuse 11 is blown,
check your (3) brake light sockets for shorts of any type, or fuse 11 will just blow again.

The brake light on my dashboard has been coming on and staying on in my 2003 Hyundai Santa Fe. What does this mean?

This can mean one of a few things.First, make sure your parking brake is fully released and not even slightly engaged.Next, check your brake fluid level.A low level will trigger a brake light.which this is probably your concern.Finally, your abs(if equipped) could be failing.More than likely it is simple enough as a low fluid problem.Have all four corners checked to make sure all your brakes are up to par and you should be ok.Hope I could help.Rate me accordingly.Thanks!!
