Not sure what you mean...
I think you're the first person that's ever refereed to it as a "count down timer".
IIRC, you can reset it through Tuneboy and like systems, but all are expensive.
A better idea is to maybe work it out with your dealer so if you bought the filter and stuff through them, they would reset the light.
Some forum members have written that their dealer charged them a nominal fee to reset it.
