What does the appearance of the oil look like? Is there any engine noise during cold start, while the oil pressure light is on? It is possible that during the cleaning process the indicator light sensor may have become dirty. Are there any other indications of low oil pressure or low level of oil?
It is not likely that the Auto-Rx has anything to due with the dashboard light warning at start up. However it should not be ignored. At start up, if possible check through the valve cover and be sure that oil is pumping to the top of motor. If so, then complete the 500 mile treatment and purge and refill.
Tell us about your vehicle, miles, maintenance, and why you thought to cleanse the motor. I have heard good comments on this board from BMW owners.
