Yes, the part number is the important bit that tells the car the Ah of the battery and maybe other characteristics such as AGM.
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.
