Technical Help Identifying this Part

[raymanlk]

Hi everyone,

I have a rare 2007 Fiat Grande Punto 1.3 Diesel Duologic (VIN: ZFA19900001351085). The Duologic gearbox has failed, and after replacing nearly every other component, we’ve isolated the issue to this specific part. Could you please help me identify exactly what this part is, so I can start sourcing a replacement?

Thank you in advance for your help.

Do your own final research for compatibility , most suppliers (inc that last one) will do a VIN check to ensure it's correct for your vehicle.
