Mercedes C230 Random False Alarm FIX

In this video tutorial I show you how to fix the annoying problem of random false alarms associated with your Mercedes Benz vehicle.

While I am working on a W203 C Class in this tutorial I just want it to be known that this solution will work on other makes and models of Mercedes-Benz classes, just note that the location of the siren may be in a different area on your specific vehicle.

If you’re looking to temporarily disconnect the siren to bring peace back to the neighborhood or while you're simply waiting for a parts replacement, that solution can be found in this video tutorial as well.

One key note here when purchasing your siren replacement:

Not all sirens have the same style of harness connector. In fact when performing my online research I ran into 3 siren horns, all with different harness plug connectors. So, that being said, it’s important that you remove your siren first, take a snapshot with your cell phone or camera of your connector style located on the rear of the unit and use that image as a reference to begin your visual internet search.

Additionally, you may run into the issue where you found the correct connecting plug as your damaged unit but the siren body, specifically the bell housing shape in the front, may differ from yours. That's ok.. pull the buy trigger and snatch that bad boy up. The difference in physical appearance from my research varies in some years, innie vs. outie in replacement parts is not important as long as the mounting holes and harness connector match, so rest assured, your good to go. 

Fortunate for me I was able to find my part from a seller on eBay and the part was in great used condition. I suggest you take that route too as the dealership prices for this small siren are very pricy.
