I posted this problem in the Technical Q & A section several days ago. Got no response so I'll try here. I've searched the site for help on identifying the cause of a beeping sounds (different from the normal chirps)that seem to be comming from the alarm siren located (I believe) below the right front head light on my 575. It started after the car had been sitting in the garage for about a week. It begain as a hardly audible sound progressing to a distinctive (but not loud) beeping over the last four days. Its periodic, at random, but constant. I took the car for a drive shortly after it begain to make sure everything was well and that no other alarms were indicated. The main car battery was fully charged and all seemed well. I parked and connected it to my battery maintainer but the sound keep going on. there is a lot of info on the site that tells me that this is probably an alarm that indicates that the "back-up" rechargeable batteries that are mounted in the alarm siren are going bad or are failing to recharge. The reasearch on the site is clear about the fix "replace the siren or the rechargeable batteries". I would like to wait untill my next service in Jan. to do this. The help I'm looking for and could not determine in the site research is this: 1) Am I on the right track or could it be something else? 2) Is the sound being powered by the main car battery or the internal siren back up batteries? 3) Will the sound eventualy stop or die bout on its own? 4) If not is there any ways to stop it in the meantime? BTW. the system has never "chirped" But every thing has worked and the lights flash. Any help or advice would be greatly appreciated. Thanks, George
Sounds like corrosion has attacked the horn unit, will probably need replacement. You can remove it and take it apart to see if this is the case. You can also use an SD2/3 to communicate with the alarm system to see what's going on.
I had similar malfunctions with the alarm/siren on my 550. The problem is due to the batteries going bad in the siren. While you can replace the batteries, I simply ordered a new siren from Ricambi and replaced it myself in about 15 minutes. Problem solved. Cost about $250. Good luck!
Thanks for your help. This site is great for that! I just ordered a new siren today ($285.00 from Ricambi) and should get it early next week. Were you able to just disconnect the old one and reconnect the new one without shutting off the main car battery or do you have to use the battery shut off switch.? I'm really having a hard time locating the siren. I can tell its around the right headlamp assembly but can't find it. I feel real stupid. Any help with this?
You don't need to disconnect the battery. Look for the siren tucked under the passenger headlight. It's about 4 inches square. Unplug the connector. Loosen the nuts on each side of the siren but don't remove them and the siren will slide out of the bracket. You can get to one nut from behind the headlight and the other from the side between the light housing and the bumper mount (more by feel than sight). Try not to drop the nut/bolt combo as they won't drop through to the floor but will land inside the belly pan. I'll try to take a couple of pictures for you today and post them. Good luck! Mark
You can see the wire and siren with one nut exposed just above the brake duct and below the headlight. The second nut is on the other side. It takes some doing, but you can get to it. The other picture is of the old siren. As you can see, I tried opening it to replace the batteries, but in the end decided to buy a new siren. Best of luck.

Mark, I can't believe my luck. The layout on the 575 at that headlamp is different than the 550. I can hear it beeping in that area but still can't find it. I took it out yesterday for a drive and after about 5 min. it stared to beep very loud (alarm type loud). I'm sure everyone in the near vacinity could hear it. Returned home quickly, pulled into the garage, in panic, was going through the manual to find the main battery cut off, which would probably have done nothing. Just when I was about to to do that, it stopped! But not for long. It started back up after about a half hour very muted again (like when it started a week ago) and has been beeping for a day and a half. Why won't this thing just die? I was going to take it in to my ferrari tech. who I called. He said the best way to get at the siren would be to remove the front bumper and that was no big deal for him. Now I'm afraid to drive it there (a 120 mile trip) should it start sounding that loud again. Right now I'm stumped. I'm used to ferraris, know and accept the problems of ownership. It's just unbelieveable that something this trivial can be so frustrating and inconvenient. I'll let you know how this adventure turns out. Thanks again for trying to help. George
That's too bad. Can you locate and pull the fuse or relay for the alarm until you can make repairs? Maybe your Ferrari tech can help you identify it. Mark
