Oil Change interval from 18k miles (30k km) to 7k miles (12k km)

[XuLeTZ]

For everyone who wants to change their oil change interval from idrive/cluster, here is how I done it.
E-Sys, replaced the 8KA (18k miles/24months) with 8KM (7k miles/12months) and code KOMBI and DDE/DME.
After that went to check FDL and change this:
(Thanks to @atzebmw)

KOMBI L7_MID > CBS_Konfiguration 3009 > CBS_WEG_FAKTOR_FZG_CHECK_DEPEND = faktor_5

KOMBI L7_MID > CBS_Konfiguration 3009 > CBS_ZEIT_FAKTOR_FZG_CHECK_DEPEND = faktor_4
Then there is a coding in the DME or DDE which depends on the engine i think.
Here i have 3 different BMW models as examples:
2L petrol ----- DME > BSU-Config 3320 > OEL-Config = Wert_14

2L diesel ----- DME__DDE7xx > OHNE_ZEITLIMIT 3701 > OWI_NEU = wert_11

3L diesel ----- DME__DDE7xx > OHNE_ZEITLIMIT 3701 > OWI_NEU = wert_15

All these codings are for the 12TKM 12Month interval.

After everything is done, you have to drive for a while for the change to take effect.
