Service Reset Problem

Re: 2008 X5 4.8i

I'm having a problem resetting one of my Condition Based Service indicators.

I have a service warning for differential fluid change. (It was just changed, but it was overdue). Whether it's a coincidence or not, I very recently used my Schwaben scan tool to reset the service indicator for brake fluid change. I am worried that the Schwaben tool somehow turned on a feature that is not supposed to even be on this car; (I was not aware there was a CBS feature for diff fluid on my car). I'm not a big believer in coincidences.

Since I just had both diff oils changed this week, I need to clear this. It is not on the list for the items I could clear under CBS with the Schwaben, nor was it on the list of what was clearable as a CBS with an Autologic at my friends shop.

I tried a manual reset of this. Maybe I'm not doing this right, but here's what I did:
---With ignition on; car not running, I held the trip reset button until the service items came up.
---The Diff oil item came up first, so I released the button, and then pressed again for 3 seconds. I got a message "OK", and that was it. If I hold the button longer the "OK" disappears.
---I was expecting to see a message "RESET" but all I got was OK.
---This did not clear the CBS warning for differential oil.
