there is a horn inside the right fender well that is one of the parts that activates the alarm system. on a u.s. car it is located inside the passenger side wheel well cover (inner liner). could you possibly give me the part #, or the proper name for the horn so i can purchase one. i've tried multiple searches and can't find the information.
thanks, harv
car is a 2004 mercedes cl600., but i believe all cl's and most mercedes cars have the same set up.

Hmm...on the USA W220's, it's located on the left side of the car (driver's side) inside the wheel well cover.

It's called an "alarm siren", and it is part #2198203226. Part fits your CL600.
