Coding the J644 module for Audi Q7

[dawoodsubedar]

I have an Audi Q7 2007 4.2L V8. Most part numbers start with 4L. Except that my Battery Management Control Module (J644, Address 61: Battery Regul.) shows the part number as 4F0 910 181 E. Should it not be 4L0 910 181 E?

I wanted to recode the module using VCDS HEX-NET but it does not allow coding of the J644 module. It allows coding only for the battery. Is there a way to code the Battery Management Control Module?

Note: The actual part number of the installed component in the car is 4L0 910 181 E.
