S320 W140 car horn got stuck causing continuous horn

[Rasim M Qureshi]

Yesterday while I was shopping with my family I pressed the horn once and then switched off the car, after 10 minutes when i started the car the horn also started, I switched OFF and then switched on again but the moment i turn the ignition ON the horn also starts causing an embracing situation, I then called my mechanic on cell he asked me to turn the security ON then OFF, but it didnt help, then he asked me to close all the doors and then open manual, it didnt work, then he asked me to remove all the fuses one by one and start the car but it didnt work, then he asked me to removed the battery cable once but it didnt work either, there was hardly any solution working, then my wife asked me to put a piece of cardbord in between the SRS and the steering wheel, and that did worked, thought with a slight jerk the horn started for a moment but by creating an artificial gap between the SRS and the streeing wheel the psoblem solved.
I was not able to disconect the horn as I had no aproach to horn. Any how next day I went to work shop and later on the mechanic discovered that the bushing of one nut in the SRS was short. [/b]
