Peugeot 307 1.6 HDi NON Start

Hi friends.

I need your opinion. I have here 307 1.6 HDi with edc16c3 and BSI equipped with 95128.

The issues:
- Engine not start.
- Dash not show mileage.
- Clim auto not light on.
- Fuel tank full but dash show tank empty.
- Central locking doors not works with key remote.

DTC's stored:
In BSI nothing.
In engine ECU just EGR fault and heating... so can't start.
No communication with COM2000.

I checked parameters in BSI:
Engine/BSI unpaired.
2 keys for learning, but key not recognized... so engine ECU not authorize start and stay locking.

Before to replace BSI, i think mileage tank clim... because car in "eco mode".
Issue can be COM2000, but how to test it for be sure?

Thanks for your help.
