Airbag Alfa 164 3.0 v6 24v year 1994

[Biagiocbx]

evening to all as the title suggests for a few days I am happy owner of a fantastic alfa romeo 164, obviously the only problem I have risen is the airbag warning light that flashes, bought on the internet a new control unit does not flash and turns on steadily .. ..do you have any advice? thanks for everything in advance Biagio
