Hi everyone,
I'm after a little help if possible with a diagram and perhaps even part number for the alarm siren on my 2009 CLK. Since I've owned the car, the siren has never worked although the alarm does quite often trigger itself. I assume that this was a politeness feature so as not to disturb the previous owner's neighbours and that they had simply disconnected the siren in favour of resolving the issue. However, having had a read through some related posts, it seems that the battery is the likely culprit and given it's age I am sure that it must have had it by now in my one so there is also a good chance that it is systematically ruining it's circuit board at the same time. I absolutely hate it when things don't work properly and after fitting a new OEM 3rd brake light yesterday, this is the last thing on my list of broken things to resolve but there is always fettling to do on these old cars isn't there?
The fault that my alarm has is that is sometimes triggers within 5-10 minutes of locking the car. I disarm it, wait 5-10 minutes for it to happen again and then disarm/rearm all is fine for either a month or until the next time I use it. I'm struggling to find a pattern for the behaviour other than to say. that it seems worse if the car does a few short journeys. The only other possible clue that I have come up with is that I noticed the interior light was on when it happened last week which made me wonder if it is a door trigger that is faulty but to be honest, I don't know if when the alarm is triggered the car turns on the interior light as part of a deterrent etc. I've checked the parking foot age from my dash cam and nothing has ever gone near the car to trigger the fault.
So, if any of you kind souls can tell me where the siren is and the part number I would be most grateful as well as any experience you have of this fault and resolutions. Most of the threads I found seem to be related to the Scorpion units from the 90's but am happy to be guided to a post I may have missed.
Also, (while I'm asking)... I see a lot of you are able to post the parts catalogue pics, I tried to register with MB for it but it seems it's no longer available for public use, is there a resource available elsewhere I might look at? Having had several BMWs I loved realoem.com as a resource but am unable to find similar for MB.
Any help appreciated as always.
