i asked steve (mbenznl) when he came to nyc last year for a weekend, retrofitted a comand in my car and crashed at my place about the chirps. he thought it was possible but when we hooked up my car to the S.D. and went to the netherlands setting as well as the other region settings we couldnt get the chirps to work. he however did get it to work on my friends 2004 e500 and some other kids 2003 c230blackbenzz - 3/31/2005 1:26 AM
you can make it chirp by changing the ECU to Netherlands mode. I personally dont know how but I'm sure someone does.
