8KA to 8KL coding

[ivanivanusic]

Hi everyone,

I want to change service interval from 30000km/24 months to the 15000km/12 months.
I saw on few pages that only milage will change with this coding but time won't, maybe it'll change after service has been done.

Can somebody cormfirm that both things will change after service?
Also can somebody share me step by step for this coding, as I have only experience with BimmerCode and not with Esys or other expert tools?

Best regards
