Headlight leveling system/clicking noise in idle
 

I have a 04 Rx8, auto transmssion... Last Saturday, the headlight leveling system malfunction light came on---was on for about 10 minutes and went off. Last week the light did not come on again until Saturday night, and it is doing the same thing...on and off. Anyone have any experience with this problem?

I have also noticed a wierd noise since I had the car in for it's 30,000 mile service and oil change. When I'm in Reverse or Drive at idle, I hear a clicking noise... The noise goes away when I'm driving, and started out intermittent, now I hear it most of the time. I had the car checked out at two different dealerships, they don't seem concerned.. Is this normal? I've never heard it until I had my servicing done. I also hear a squeal sometimes when I start up the car, that goes away after about 2-3 minutes, that never was there before.

Thanks in advance!
