I have a 04 face lift 166 the full beam headlights don't work.
looking at elearn I need to check the relay and fuses located in unit B3
but where is it I cant see the unit located in the wing.

As you stand in front of the car its on your right hand side by the water expansion tank I believe.

Always thought it was odd to put all the fusesby a water tank to be honest .

In mine, the relay in the wing is for the fan. Once I removed it and the car lost all the power, I barely could hit 2500rpm, in 1st gear.
In Multiecuscan it clearly showed fan error, pushed it back and cleared the error, power back.
Mine is a JTD, knowing Alfa, on petrol it could be totally different.
