There is a thread on the Fiat Commercial Vehicle Ducato section [name may not be accurate, but may give you the general location] stating that Fiat had a problem with ECUs in 2015/16 and that replacements since then appear to have a more robust constitution. Our 2016 ECU failed in November 2021 [Burstner Ixeo 590] but the cause was a low Starter Battery voltage [it had been changed 6 days earlier to avoid an ECU failure but was a duff new battery]. Cost £855 for fault tracing, ecu purchase/recode and wiring trace to identify a back charge that caused the Starter Battery to back feed to the Leisure Battery via the Electrobloc and a 3rd replacement Sterter Battery because the 2nd new battery had been damaged by the backfeed.Had the usual air bag failure light (2016 Ducato/Buestner) possibly.low 12v when starting, Fiat Bournemouth were of little help other than stating an outrageous price & offering no help in contacting Fiat.
I phoned Fiat who replied "its an old van" implying "what do you expect! "!
Took it to Essandjay who confirmed the fault was the unit and not the wiring. Had it repaired under MD&G warranty, but here's the thing - the new ecu has a different part number and manufacturer. Clearly Fiat know there's a fault within those years, and have since changed supplier. The mechanic also said they had never had fault after fitting the newer version ECU.
Problem solved by spending some more money in Jan 2021 to get David of Wildebus to fit an AMT12 Battery reconditioner that forces the Leisure Battery to feed the Starter Battery with a constant supply and then replenishing itself from the Solar Panel Feed
