good morning

today we present a solved case in the help desk

the machine was taken to the workshop for  eobd light on with engine in recovery and low power

The following error codes were present in the diagnosis

P0101: Air mass sensor/air flow volume sensor - range/performance fault

P0401: Exhaust gas recirculation - insufficient flow detected

we suggested reading the parameters of EGR opening and air intake mass at idle with EGR open and closed.

Later, after dismantling the egr valve and its piping, we found a blockage in the EGR duct as shown in the photo

Happy reading and warm greetings from Antonio and the Magneti Marelli team
