On my 1995 C280, I have the buzzer sound when I leave the lights on, etc, door open, seatbelt reminder, instead of the beeps. I want to make everything beep, that buzzer really drives me nuts.
THis is what I did. I went under the drivers footwell, removed the panel, and located the buzzing sound with the door open and key in ignition. The part number is 012 545 68 32, and it was made by Hella. I could not locate the beeping sound because I have to have the car in motion with the Emergency brake on. I thought it to be too dangerous to put the car in motion with my body under the dash and have the car rolling down a hill! So naturally, I could not locate the beeping sound.

I want to know.... can I put the beeping sound thing (if i buy another one) into the existing wire connection? Is it the same size, hookup, voltage, etc? Will it work to connect it to where the buzzer was? Anyone know the part number?

That buzzer drives me NUTS. I am also going to wire an On/Off switch into the underside of the dash to turn it off if I have the door open or something. Thanks guys
