there is no problem since your byte 18 is known 04, problem is when byte 18 is 00 (it newer is a 00, 00 is just a mask, true value is hidden)

susjed neznam sto komplikujes stvari, iscitaj sa vcp-om eeprom modifikuj vrijednosti da ti rade i unutrasnje kao kociono svjetlo i gotovo, u slucaju da sta zaseres upises 04 u byte 18 i mozes opet testirati do mile volje, ako te toliko strah da diras byte 18 nemoj nista dirati nadji ko smije i nek ti odradi....
ps. answer written in native language to summarize I explained that he can revert to 04 in byte 18 in case of any issue.

after editing with vcp byte 18 won't be 04 so don't change it just leave it at 00

For 5K0 BCMs, when you do changes in EEPROM, byte 18 change to 00
For 1K0 BCMs, when you do changes in EEPROM, byte 18 don't change, if you wan't to view your changes you have to change to 00 before.

All options of byte 18 are in flash files, I have passed all the info to Excel file:

In line with value 04 you can see what is used in our car. At any point if you change byte 18 to 04 it will use those values.
VagHelper is a great tool to understand what those bytes do.
