Hi.

You had a problem with the com2000 and changed it.

Now the headlights don't work as they used to and come on with the key and you have no main beam.

I would start with lexia (info here) and check the BSI is configured to communicate with the replacement COM2000 unit because it sounds like a communication issue you have.

Either that or another faulty com2000, but lexia can help you with that too .
