Chirp Chirp Chirp
 

Another question about my new machine. When I turn the motor off I hear a real fast sound like Chirp Chirp Chirp Chirp. And then silence. Like an old panel station wagon but not as loud. What is it?

Release of pressure from the ABS system as electric to it is cut off.

ah come on Jim...you can do better than that. :D

Thanks Dr. Curve. Good to know it is normal occurence.

Well.......O. K. Bob, but just realize that most people are not aware of BMW's out sourceing for certain parts. In the case of the ABS relay switch system they sent out bids and the final one was rewarded to "Humming-Bird Electrical Systems" located in southern France. They work great but PR staff of their (HBES) small firm felt that they needed to uniqueify their product from others, hence the patented double chirp chip was infused to signal their product was being used. Strange......but there you have it.
