2000 BMW 540I Complaints

The audio suddenly stops and my turn signals also stop working. When this happens when I'm in traffic, this is very frightening because I cannot signal lane changes or turns. Turning off the ignition and restarting the car always fixes the turn signals but only sometimes fixes the audio. It usually takes several restarts before the audio works. When in the failed condition with no audio and no turn signals and the engine running, disconnecting the Dynavin D9 "ibus box" from the vehicle instantly fixes the turn signals but not the audio. It has not been reproduced or confirmed nor has it been inspected. There is never any warning before the problem appears. I have been in continuous contact with the manufacturer in California. They sent a new ibus box, hoping that would fix the problem but it did not.

Car had sat for about a week since I had driven it. I opened the driver door, inserted the key, and turned the key to the starting position. It failed to crank after the dash lights lit up and then the driver steering wheel airbag deployed in my face. The car was on flat ground and the temperature was not extremely hot or extremely cold. The previous several times I had driven the car there was no indication of an SRS light and the car started perfectly every time.

I needed to move the car after it was sitting for about 3 weeks. It would not start due to the battery was run down. As soon as I started charging the battery, the front passenger airbag exploded causing extensive damage to the dashboard and windshield. Thank god my wife was not sitting in the car. I have not contacted anyone about this. It happened a few hours ago. It is about 93 degrees with very high humidity. I am sending this report because someone could have been killed.
