Two reasons at least IMHO, one being the heat soak in that area is much lower, and secondly if its hidden there it is much less likely to be tampered with by someone wanting to take the car.

George, I won't be shipping you the batteries. I just checked them, and they are all 3 pin batteries. Not 4 pin. So, my mistake. Like I stated before, we are foregoing the alarm altogether. One less annoying thing to worry about. Later.

 

OK, no problem.

 

I installed a new siren and it now chirps but it is very quiet. You have to be within 20-30 feet max to hear the chirp. The siren however is extremely loud.


Is the chirp normally this quiet. It is much quieter than any other car I have ever owned.

 

Yes quite & has a different sound ! I like it ! Other cars use the horn for the sound not ours !!!

 

The alarm module was removed after the alarm kept going off for no reason at all.
Looked at the alarm module and the batteries in the module was damaged.

My crossfire also had lights coming on the dashboard etc and odd things kept happening and it was this module that caused it.

Running the car without the module and its never been better!

 

#15 is not a good link anymore.

 

That was an old post. I see you are new - this is a great resource for information - just use the search and you will find almost everything!!
alarm siren was:
Mercedes #A 171 820 25 26 subs to A 219 820 32 26
Chrysler #5124443AB
ECS tuning #ES1779675 /2198203226

search ebay or the net or call around for the current local best price.

the new ones all require an 8mm nut that is not included for mounting
And don't forget you need a security TX30 torx for removal (hole in the centre)
I've done a couple and the hardest part is usually getting the wiper arms off - will probably require a small puller.

And you have a great resource and group in your area NWCrossfireClub https://www.facebook.com/profile.php?id=441428485887343

We even met up for the tractor parade at Christmas in Lynden - make sure you join - lots of local help and runs and info on the big July Run CCAA7 in WA

Welcome and Enjoy!

Here's one under $100...

Alarm horn for 2004 Mercedes-Benz CLK320 1718202526 Confidently purchase online now - it's quick and easy.

 

Hey guys, that original link to buy the Siren Battery module has been removed. Can someone please let me know what the part number is?
Thanks guys.

 

LOOK at my post right above yours... p/n 1718202526

 

Thanks ala_xfire
I followed your PDF instructions to get to the alarm module and disconnect
Took about an hour in my driveway
The metric socket set I bought long ago came in very handy

As a general note on repairs, I found that independent Mercedes repair shops are usually willing to work on Crossfires
If anyone needs a reference in the Cincinnati, Ohio area, I can provide one

Thanks

 

You are most welcome !

Have you noticed we've skipped a few easy ones for you to answer? Trying to help get you up there my friend!

BTW, if anyone is interested I have a set of two brand new Original Varta batteries as described in this thread for sale ...$21 shipped.
I purchased the batteries but once I opened my module the PCB was too corruded, need to replace the whole module.

 

Hi I've just started driving my dads crossfire as hes passed away like most of the comments ere the alarm goes off when it's been left for a while the alarm sounds quite crocky almost like there is lack of power so I'm guessing it's the alarm module so I've ordered new batteries to replace them in the module as I havent taken it off yet but my question is if I disconnect the module will everything still work othree than the alarm or will it just be like I've taken fuse 9 out and not be able to lock the car and have the horn disabled

 

You can disconnect the alarm module, no problems.
The chances of being able to replace the alarm batteries are about 1 in 20, usually the old batteries have ruptured and destroyed the PCB.

 

If your alarm is damaged like you say then I would guess that it is ruined. The trouble you are having is because of the damage done by the leaking batteries.Get a new siren. The cheaper ones just flash the lights and the more expensive ones sound a beeping noise as well as the flashing lights.

The time to replace the batteries is before they leak not after, these batteries are old so replace them or the sirens now, do not wait for them to leak. If you are taking the sirens out to fix them do the job once, not twice. I fixed my siren before it leaked but then decided I wanted a beeping siren.

 

Ok great advise well I'm going to take it off tomorrow and see how things look cheers guys just one thing are these modules worth buying second hand like ebay or am I going down the same road asking for the same trouble would you recommend me buying second hand and before I put it on change the batteries anyway also that way I can look inside after buying and if it looks bad I can send back to the buyer
