Started the car and drove about a block and the siren came on and off. Started to see a faint grayish smoke on the battery side. Couldn't find the source. A continuous clicking noise persisted for about 2 minutes on the driver side under the hood. More like under the wiper/ fire wall area. The car was fine when I parked it for approx 3 months. The only thing I did was put trickle charge on it and disconnected the battery

 

You will need to remove the wipers ( may need a puller ), then the the wiper cowl.
Located about in the center is the alarm module, unplug and remove.
You can either go on without an alarm or order a new replacement.
Search on here for "alarm" for the MB part number.

( clean out all the leaf debris while you are in there, check the drains are not clogged )

 

Is that an expensive part and is there anyway to chk before replacing. Would that have caused the grayish smoke?

 

Kinda, yes and yes.
To really check you have to saw the module apart.
They cost $120-$150

Thank you

 

Hello fellow George, Just what is a lifetime warranty on an electronic device? I know the batteries don't last maybe more than 10-12 years, would they (FCP Euro) replace the siren after it craps out? I would buy one for sure if they did BUT....

I'm pretty sure they would, it's a marketing gimmick they use to beat the competition, any negative feedback on it would impact the image they want.

 

They have the odds on their side, who keeps a car or even the invoice for ten years so any new owner is out of luck.
