How does the E36 "oil change" lights work?

[danieljames]

Hi fanatics. Just out of curiosity.
With regards to the 5 green bars/1 yellow bar/1 red bar to show when an oil change is due on the e36.

please note this is not from my car


How does the computer decide when to drop a 'block'? I service my own car every 10 000km. Last time I reset it was on 270 000. I didn't bother resetting it at 280k because I know that I'd service again on 290k.
The reason I ask is because, when I reached 280k, I had 1 green block left and now on 290k it's still only on the yellow block and hasn't gone down to red.
Does it somehow monitor the condition of the oil? I warm my car up by driving very gingerly and only hammer it when she's properly warm. She gets hammered on a daily basis. Just as a note I only sit in traffic for about 30 mins at night.

Thanks chicks and chaps

As far as I know it's mainly two factors:
1. Engine temp
2. Revs above 4000(?) RPM

with low temps and high revs causing earlier service schedules.

I think so to and time.

The LED globes are connected to the car's electrics via a positive and negative wire which create a current and in turn makes the globes light up.
