Re: Siren Alarm goes off in middle of night
having the same problem. after some checking, it's likely the siren. after checking my alldata information for my slk, it is located under the air intake, the plastic cover under the windshield wipers, and is located on the passenger side. I will order a mercedes part #003 542 68 20 which is for a 98 slk to save a little money and is supposed to cost about $45. A cheap and easy try and I will let you know if it does the trick or you may want to just go ahead and try yourself after what you've been going through because it is an inexpensive try. BTW you might pull the negative side of your battery with the alarm deactivated at night to make the neighbors happy.
