Passenger Restraint System Fault

I have a 2004 645ci and I am receiving a passenger restraint system fault. Does anyone know what could be causing this? My airbag light is one because of it.

If your battery has a bad cell, it can happen. The code will have to be removed by someone, with the proper tool.

That's what I thought originally. I got the battery replaced and it went away for a few hours, but it eventually came back

Did you charge the battery after installing it in the car? If the battery is not fully charged, the fault will not go away. It took mine 12 hours to charge, to clear the code. You will also need to register the battery to the car, to make sure it gets the charged correctly.

They put in a brand new battery so I didn't think that it needed to be charged. Is there something that they needed to do I addition to installing the new battery?

like HerbP said you need to register the battery to your car for it to run perfectly

By registering the battery the car knows the age, charge cycle and proper current for the battery.

Registering it will extend the battery life. Not registering will not alter the car's performance.

It should cost $30-$50 to have an indie do it. It's a fast process.
