W213 Adblue Tank part number?

Hello everyone. I need to replace the adblue tank on my W213 E220d 2017, and I'm struggling to find the specific part number without disassembling it. I made a search with my car's VIN number, and there seem to be 2 numbers. I can't figure out the meaning of the the replacement dates showing in the details: Any ideas? Thanks
