It is a new part number. I'll try attach pictures of the new and old. The numbers are different. Old first, new second.My local dealership texted me to say the EGR cooler assembly has arrived. I've got to set up an appointment to get the car to them for 4-5 hours and we'll see what happens. I'm going to be asking the service department guy if this new part has any changes (updated part numbers) to see if there are differences from the stock EGR cooler.
