I have a 2004 coupe with auto transmission.
I have to replace my alarm siren because the circuit board is fried to a crisp.
The fried board never "chirped". I already have the $5 mod mentioned in the PDF's. But I want my replacement board to chirp.


According to the search function, I can get the chirp if I replace my toasted siren with #51244443AA. The problem is; I cannot find a source for the AA version of the siren.


My search also mentioned MB part# A219 620 3226 as a suitable replacement. I can find this siren at several sources, but none of them can answer if this siren chirps.


I've been to Benz World, SLK 320, and other sites but no one can tell me if 3226 chirps.


Does anyone on this forum know if the MB- 3226 chirps?
Thanks
