Multiecuscan

Hi All
Newbie here
I have a 2009 Fiat Ducato 3L and my question is this.
Is there any diagnostic software/programs suitable that i could install into my laptop to run check and make any adjustments on my Ducato.
Something that a layman like myself can learn to operate

Yes there is: MES MultiECUScan

See: https://www.multiecuscan.net/SupportedVehiclesList.aspx and look for your Ducato there.
