Prior to the light coming on, were you ever awarethat one of the automatic regens was taking place. You should have seen changes to your average MPG, your idling speed Gals per Hour and your coasting MPG.
You normally only get a light on after several auto regens have not been completed. You first get a steady light warning you about the filter beginning to fill up and then you get a flashing light telling you the filter is almost full.
In any case. you should get it back to the dealer as soon as possible.
