2002 BMW 320i

Hi Guys, got a 320i Canadian car. It had the abs light on and the ASC lights on, this car does not have DSC. diagnosed the problem for code 5DF5 ecu internal fault control unit internal failure. Sent the abs module to BBA in Toronto and they told me they couldn't repair it, They supplied me with another unit they got from the states. I put it in and recoded it using Autologic scan tool, coding was good but I still have 2 yellow lights on the dash for the ASC. Codes I'm getting are 5e1F vin #different, 5E20 and 5E21 pressure sensor 1 & 2. 5E1E steering angle sensor and 5D8C DSC sensor can time out. I try clearing codes and they keep coming back. Looking in to it more I feel there is possibly a problem that the module that they sent me as it does not have DSC and it asks me to reset the steering angle sensor which I cant do. Anybody saw this before??? thanks John
