I just had my DU replaced under warranty. Need help decoding the part.

[tony.tone]

I just picked up my 2015 MS 70 after an MCU2 upgrade and having the DU replaced under warranty.

According to the invoice I received this REMAN unit

ASSEMBLY - REMAN - BASE REAR DRIVE UNIT
- LDU(1025598-00-U)

I saw post about the -T and - P units but nothing about U.

My question is, did I receive a manufactured 2015 model drive unit or a newer version?

Thanks geniuses.
