---BMW airbag light is on??

Hello.
I have a problem with airbag on BMW 320d(e46) made in 2000.
The error for the first time was a litle bit strange for me, but it has a
logic.
Here is the scenario.
If somebody sitting in the front-right seat the Airbag light is on. Not
allway, just sometims. Depending on the sitting position in the seat.
We removed the seat to see what is the problem. And we found out ht
following thing.
There is a cable connectet from the floor into the seat main connector.
From that main connector goes one part to the seat belt sensor and the
second part goes into a black box, and from this black box two wire goes
into the seat.(There is a pressure sensor. I think).

-I thought maybe there is a contact problem between the wires. And I tried
to move them, but nothing.

-I removed the connection betwen the black box and the seat main connector.
Then the airbag light was on.
-I connected back the connector and the airbag light goes off.

-I removed the connetion between the Black box and the pressure sensor. Then
the Airbag light is on.
-I connected back that sensor to the balck box, and the airbag light was
off.

-When I removed the seat main connector(to remove the seat from the car) the
airbag light goes on. Then I connected back and the irbag light remaind on.

I found where the problem is. The problem is with the pressure sensor. When
somebody sitting in the seat the wireing in the seat is broken.

The connectionsw is same as before, but now the airbag light is allways on.

What do you think. why the airbag light remaind on?
-Maybe the car memorized in the ECU the airbag problem?
-Maybe I have to clear the error code from the ECU to switch off the airbag
light.?

Do you have any kind of PC software to read out the fault codes from BMW
e46? (320d)

Any advice are welcome.
