Ahh ok so the 04 is the current date for my next oil change, which is set as the value for COU_RSTG_CBS_MESS_WERT when you read the current status.

I made these notes in notepad copying and pasting from other sources but also wokring out what worked for the e90, to compile these steps (so sorry its in mixed tense/third person etc in places). The prg file I found that worked on both was MSD80.prg, I couldn't find that information out there anywhere.

Code:
1. On both cars (E82 and E91) open Tool32
2. Load MSD80.prg
3. Navigate to cbs_daten_lesen and run the job
4. In the results, find COU_RSTG_CBS_MESS_WERT make a note of the value here, it will be between 0 and 30. This value will be needed later on if you decide to adjust the month/year manually. The below screen capture is of my car, notice how the value here is 08. This value is the number of times the CBS oil counter has been reset, so my car has had the CBS oil counter reset 8 times, or has had 8 oil changes done in its life time (assuming the CBS reset was done correctly each time the oil was changed)
5. Step 6: Close the results and navigate to cbs_reset. In the Arguments box, enter oel;XX;YY, where:

XX = the service interval (Approximate percentage of the original value, in multiples of 1. The 100% value is 27,580km)

YY = your current CBS counter value

6. A few options for XX, in increments of 5, are:
oel;50;YY=14,000km (13790km rounds to 9,000 miles)
oel;45;YY=12,000km (12411km rounds to 8,000 miles)
oel;40;YY=11,000km (11032km rounds to 7,000 miles)
oel;35;YY=10,000km (9653km rounds to 6,000 miles)
oel;30;YY=8,000km (8270km rounds to 5,000 miles)
oel;25;YY=7,000km (6890km rounds to 4,300 miles)
oel;20;YY=6,000km (5510km rounds to 3,700 miles)
oel;15;YY=4,100km (4130km rounds to 2,500 miles)
oel;10;YY=2,700km (2750km rounds to 1,700 miles)

To pull this all together, my counter value is 08 and I want an oil change interval of 8,000km, so I entered: oel;30;08 

7. Navigate to cbs_daten_lesen and run the job again, view the info and look for a change in RMMI_CBS_WERT value. This value is multiplied by 10 to give the OCI, ie 827 x 10km = 8270km for the OCI.
Thanks for the detailed response! I know this is a small thing, but its been nagging me since I bought the car and I've always wanted to change it. I'll be giving this a try this weekend.
