Hi, I've been having problems with my indicators flashing randomly when I park my car. At first the siren used to make a noise, and then it became a croaking cricket like noise. I have read a few posts indicating that the problem might be due to the Alarm Control Module's battery running low.
Admittedly, I have had my car for approximately 10 years so I am not surprised if the battery has gone flat.
I then noticed that the indicators would flash, and then get stuck on being on solid and this was initially resolved by locking, unlocking, locking, unlocking the doors.
Now, it doesn't seem to respond and just the left indicator is left turned on. I decided to buy the 2 x Varta 3.6v batteries that are contained in the ACM (Alarm Control Module) as the ACM costs $480 AUD from Mercedes Benz. I have since disconnected and taken out the ACM from the car, but the left indicator light is still turned on.
Will the fixed ACM with new batteries resolve this? Or do you guys think that this might be an indicator fuse (which I don't know where it is located)?
Any help would be much appreciated.
Thanks guys.

George.
