Steve came round tonight to solve this fan issue, tested the fan via MultiEcuScan on actuator test, the relay was clicking during operation, so power is being sent to at least the relay but the fans motor wasn't spinning.
Next tested the fans motor resistance, came out to 35ohm roughly, at first i thought it was a bit high, my fan was 0.9ohm, but we then tested the fans variable speed resistor and it was 'OL' at first, i swapped it with one i had knocking around and tested via MES and it worked!
Tested the resistor again (see picture) the resistance is way too high, the rating for it is 0.3ohm.
So for anyone else that has radiator fan issues, test the fan speed resistor first.
Thanks you the Alfa Owner Forum, We managed to sort out the problem with Steves 156.
All the Best, Chris
