What does it even mean you cant connect? Did you go to Repair in Diagbox?

It means no communication with engine control uni

Update. When the ABS module is disconnected. I get start. There is a short circuit in the can bus inside the ABS module. Next problem is that the dynamo does not seem to be charging.

I have attached the "starting" wiring diagram for your car which includes the alternator. My guess is you have a faulty alternator. However, there is a control line (wire 1030) which is described as "Charging indicator activation commend". This connects to the alternator via a black two pin plug. It would be worth checking the voltage at that plug.

The important blocks in the diagram are:
PSF1: engine compartment fuse box
1020: alternator
1010: starting motor
BSI1: Built In System Interface
0004: Instrument panel
CA00: Ignition switch
