if the buzzer is going, that should be the .9bar sensor near the oil
filter. I had the local loser garage change my oil once and they knocked it
loose, probably while changing the filter. Scared the crap out of me
because it doesn't start buzzing till you hit 2K RPM, by which time I'd
pulled into traffic... Check yours-- it might only be that.
