It is likely that you have a defective ABS sensor. You should get a VAG-COM reader to see if the ABS module has failed. It's cheaper to buy one than to have it checked at the dealer. If it says that the ABS computer is dead, DO NOT BUY A NEW ONE. They are something like $1500 to $2000 and there is no need for a 2000 model year car. Instead, visit
www.CheapABS.com where a guy named Matt fixes these things. You just follow the directions to remove the ABS module from the car. Then mail it in to him (there is a form to fill out, etc.) and he will repair it and return the module to you. While it is out of the car, it is likely no different than what you have today. I should have said this above, but to verify that your ABS module is dead, the next time it rains, or if you have access to a dirt road nearby, drive somewhere that there is no traffic, and get the car going about 20 mph and then STOMP on the brakes as hard as you can. If you skid without feeling/hearing the ABS pumping away, your module is dead and CheapABS is the $150 solution. If the ABS works, then it is something else... possibly a wheel sensor, Sometimes you get a flashing brake light because the fluid is low. That one is a super-easy fix... top up the brake fluid. But that shouldn't light up the ABS light, which is why I think it's the module.I have used Matt twice. Once to fix a module, and once to get assistance (was not related to the module). He's great. I've got a BMW 530i needing the same attention, and will use his services for that as well. And no... I'm not Matt. Just a happy customer of his.
