SIA: 3038 1 what does it mean?

[tricad]

Have my 03' X5 3.0i for the crankcase vent (smoke issue) service. The $tealer guy found fouled oil in the spark plugs while fixing the separator valve as well. One thing let to another, the spark plugs were replaced, the serpentine belts (both) were replaced, and fuel injector service was done. The odd thing now is the "service engine soon" light is on. Tried the reset by depressing odometor stalk while turned key from 0 to I position and noticed "SIA: 3038 1" with 5 green light and "oilservice" displayed on dash. There's no "reset" or "re" displayed or flashed. The next depressed showed "end SIA" but the "service engine light" is still on and unable to reset. Anyone has knowledge about this "SIA: 3038 1" oilservice message, please share your explanation and thoughts. Any major issue happened here or it's just the oil service reminder? Please help, thanks!
