Now that everyone has helpfully told you what it is for, there are 2 easy checks.

If the temperature reading seems pretty accurate, it is not likely the temp sensor (right next to the driver side foglight). "Bongs" should happen at 38F. If the temp is not working correctly on the display, I'd swap the sensor and see if that fixes it.

Checking the chime is also easy. Shut off engine and remove key with headlights still on. You should get a warning chime and light on display. If your chime is out, it can be replaced fairly easily. It is usually located on the underside dash panel above the driver's feet.

If the chime works and the temp sensor is OK, I think it is a bigger problem. I don't believe it is an option, even in the coded ODBC system settings.

My .02, worth what you paid :)

when I bought my 530i it used to make a 32 or maybe 38 degree warning sound. Now, it doesn't do that. What would the problem be?
