Error file ifs

[Ludovic10sa2i]

Hello,
I'm trying to install Android Auto on a PCM3.7 (2019 Porsche Panamera).
Here are the patches I found:
MHI2_ER_POG24_P5135_MU1417_PATCH (I changed the directory name because it didn't say "PATCH").
The log file tells me this, and I don't know how to do it:

**_**MMX-flash-done!
OK: Patch folder /net/mmx/fs/sda0/patches/MHI2_ER_POG24_P5135_MU1417_PATCH found on SD card

File found in patch folder
File MU1417-ifs-root-part2-0x00ba0000-4006F400.ifs neded to patch this unit
Header size on unit - 4006F400 - does not match patch files size - - or stock - - image**_**

can someone help me understand?
thanks.
