Oil Service Reset - "OK" ... NOT!

[mejim707]

I haven't posted in a long time. I have an E70 X5 with 230k. The last two oil changes I've attempted to reset the oil service milage. I know the reset procedure. But, when I reset, it first says "Reset?", I press and hold and the reset goes away setting the milage to "---". But, when I turn the car on, the milage is what it was before. So I attempt to reset it again and it simply says "OK" in such a condescending tone like " 'Ok'.. you already tried to reset but 'aint gonna happen"... Each time I try after the first attempt it always says "OK" but the reset does not work.

I'm not sure what's going on here. The vehicle runs like a top. No codes or service alerts. But I am simply unable to reset the oil milage.

I've seen people say that the oil level sensor could go bad and cause this, but the oil sensor seems to be working just fine as is senses the oil, and when I add more it will increase the level on the monitor.

Any help trying to figure out this anomaly would be great! This isn't affecting anything other than the annoyance of the milage creeping down to 0. I just want 100% functionality!

Thanks in advance all!
