Brake Electric Antilock problems of the 2000 BMW 323

I brought my vehicle in to have a problem fixed with the sun roof and mentioned that I had a problem with steering the vehicle during braking at slow speeds. When I got the repair list back from the dealer I noticed that they had replaced a major portion of the braking and steering system. The service seemed rather familiar with the problem and didn't hesitate to replace all of the componets which leads me to believe that they are aware of a signifigant problem with these vehicles and have not reported it. I have been checking the BMW websites on the 3 series and have found that a large number of these cars have the same defect in their vehicles. The manufacturer is paying for the full replacement of the defective systems, but, only if you ask about the problem. They are not currently notifying individual owners of this problem to have this condition corrected prior to the complaint.
