So I plugged in my Autel 519 OBD2 Reader this morning and no fault (Permanent) codes where identified, the Autel 519 did identify DPF had a flow restriction problem and an Fiat Specific code was also show $80 which after Googling seems to relate to EGR valve .

The DPF warning light is still showing so looking most lightly a DPF / Regen / Clean DPF issue.

Time to order a bottle of STP  (Diesel Particulate Filter Cleaner) and a Spray can of Wynns Diesel EGR and Air Intake Cleaner, to see if a good run and spraying the Air intake hose (beyond the air filter) will bring the Fiat back to a normal running condition
