I recently purchased a 2000 ML320 and love it. However I do want to make some minor modifications. I just saw an article in the "How to" section about making the alarm "chirp" on a C230K and was wondering if this is available on the ML320. Mercedes Benz of San Diego says its not. Does anyone know if this is possible?

I have not heard of this on any other MB than the W203 C class. The W209 might have it since the 203 and 209 are closely related. I would guess that the ML would be the least likely MB to have it, since it is not related to another model.
