Like always start by choosing the profile and read ZCS on either module holding it. I would save the original ZCS somewhere before making any changes.
- After reading ZCS press F1 (Enter ZCS)
- Make changes to ZCS, remove last check digits and check “Calculate check sum”
- F6 (Back)
- F4 (Process ECU)
- Choose propriate control unit (EWS and IKE/KMB hold ZCS), then OK
- F2 job -> ZCS_SCHREIBEN (=Write ZCS)
- F3 (execute job)
Now you have the new ZCS saved code all modules (CODE CAR). Alternatively code (SG_CODIEREN) only LCM, PDC and AHM which in this case are the only modules which have any parameters regarding those added options.

So, i got a chance to check, and after a bit more digging i think i figured it out. So my original values were:
gm 81530080w
sa 2029801100856a0ff
vn 0000007ab72
I then removed the last digit of each line:
gm 81530080
sa 2029801100856a0f
vn 0000007ab7
Then Summed the Bits you mentioned previously:
gm 81530080
sa 20298
2110085
Ea0f
vn 0000007ab7
Selected calculate Checksum and OK, Giving me new values with Check Bits at the end:
GM 81530080W
SA 202982110085EA0F5
VN 0000007AB72
And did not receive and error this time. I didnt realize initially that all 3 lines had a check bit at the end, as does my VIN(FG) which i did not remove during the edit. Does all of that look correct??
