Well, I dunno if i'm crazy, but I just noticed my car's doing that at start up, with no engine lights on.
My check engine light used to come on because of my gas cap. Drove like that for about a month cause I was too lazy to buy ANOTHER cap since I was already on my second. One morning though, my light just didn't come on. Awesome!
However, that stupid "ding" is still present.
I start up, idle for about 5 seconds, no check engine light, and my car dings at me! All the time. Never fails.
I know the check engine bulb isn't burnt out, cause it's on when my engine is off, but the ignition is in the on/accessories position, along with oil light and seat belt light and gas light and all those.
Uhm, do Neons always ding at you when you start up, even if there isn't a check engine light? Maybe I just never noticed it before...and having my check engine light on for so long just made me more aware that it does that.
