Engine tap at start up with oil light.

Took the car out yesterday and got the tapping sound with the Battery light on this time. Shut the car off and restarted and no tapping or battery light. After an hour, i ran it down a nice long straightaway with no cops, the rear spoiler light came on but no tapping. Pulled over but the spoiler was down and light still on. I manually raised the spoiler and one side went up while the other side was stuck and I heard the familiar tapping.The spoiler retracted ok and the light went off after restart. I'm glad the sound wasn't coming from the engine but now I need to troubleshoot the light issue and probably lubricate the spoiler mechanism to see if it corrects the uneven extraction.

does anyone feel the spoiler makes a difference? I thought they were more for front engine mounted cars where the back end was light. I would think with a mid engine vehicle it would not be as useful.
