The serial is irrelevant it just tells the BEM it has had a new battery when the serial number has changed from the previous value and doing so resets all the parameters. So they probably are a genius afterall.
What is your part number? Something like 4E0915105A is correct but first 3 digits may be 000.
For 95Ah AGM I would go with 3D0915105G which is for the VW Phaeton.

Thanks for the info
Yes, you are correct about the part number, it is exactly like you said
So, I leave the serial as is, but put in the part number 3D0915105G,
Eventhough it is a 110 Ah battery?
