ASC light has been on on my dash, and the switch wont turn it off... Any help?

Today I flushed the cooling system, the previous owner of my 97 M3 used green coolant, and I am also missing the aux "pusher fan". I got the blue stuff from BMW along with a new reservoir and upper and lower radiator hoses. When I was installing the hoses I found it easier to access the clamps with the K&N cone filter and elbow removed... After flushing the block and radiator with water and capping the system, I filled it up, bled the tank as described...lots of bubbles came out.... Added a little Water Wetter to the mix and seems to be working good. Only concern is that the O-ring on the the radiator cap on the inside threaded part came off and was resting on the new reservoir. it fell in the reservoir.....problem??? The main concern, when I assembled the system and began to add coolant/h20/waterwetter I ran the engine to open the thermostat to suck the coolant into the block while bleeding it. Only thing is that I left the elbow and the KN filter off while running the engine, and now the ASC light is on. I cant get it to turn off. This happened once before when I removed the filter for cleaning but I was able to tap on the injector terminals and disconnect/reconnect the battery and the light was of, unless turned on. Ever since running the engine w/o the filter and inducing new coolant the ASC light has been on on my dash, and the switch wont turn it off... Any help?

To clear the ASC fault, you will have to read out faults using a BMW scan tool. Address the problem that is setting the fault codes, then clear the fault codes using a BMW scan tool.

As far as the )-ring goes, I would fish it out so it doesn't end up lodged inthe cooling system somewhere.
