Brake Light problems of the 2005 BMW 530

I purchased the vehicle from someone. The passenger restraint system malfunction signal on computer has come on, the brake pad malfunction warning has also come on, along with the left brake light malfunction! I have tried to have BMW honor the warranty on the problem with the passenger restraint, to no avail! I have asked the service advisor several times, they are saying I needed to pay to have this done, although it was still under the terms of 10 year rule! the light and brakes are fine, however I can't figure out why the computer says otherwise, unless there are some undetermined problems. The brakes and sensor have been replaced! the light is working properly, yet the computers reading differently. I have asked on several different occasions about the passenger restraint, the female sales advisor states I have to pay for this!.

This has been happening to other 2005 BMW 530i owners. While braking vehicle idrive gave warning that rear driver side brake light failed and then that the rear light had a malfunction. Upon looking at the wiring harness attached to the taillight bulb carrier, the brown wire is burnt outside of the harness. The rubber coating of the wire is burnt through and the wire is exposed. The plastic wire harness is burnt and melted. The taillight bulb carrier is also burnt and melted. Exactly what has happened to my car. The ground wire has way too much current on it resulting in melting and possible fire.
