Hi, my engine management light came on while in France this year on my 2.3 ducato 2019 motorhome - took it back to Fiat professional garage who tried a software update- lasted 10 miles and came on again! Code was P053C which is “ positive crankcase ventilation heater control circuit high” on my second visit I was told I need to replace the PCV “blowback valve” part number 5802052418 cost £115 but on back order Fiat garage have no idea when they will have the part weeks? Months? They told me ok to drive ? Does anyone know what the issue is or where I can get this part? See pic below , it sits on top of engine.
