Alarm system problems with a 2022 C3 diesel: Possible cause additional battery?
(Translated from German)
Summary of the thread
The issue revolves around a malfunctioning alarm system in a 2022 C3 diesel vehicle, suspected to be caused by the auxiliary battery of the anti-theft alarm system. A similar problem was experienced by another individual with a 2019 C3 diesel, where the siren wouldn't stop due to faulty contacts in the auxiliary battery. The solution was to replace these contacts, which resolved the issue completely. It was suggested that the same could be the case for the 2022 C3 diesel.

Hey, it sounds like you had exactly the same problem back then as I have now with my C3. Do you happen to remember how much all that fun cost you? And were there any other problems afterwards or did everything work smoothly? Thanks for your reply!

Hey, exactly, that sounds pretty similar! When my mechanic replaced the contacts on the siren due to the defect, it cost me €235. It was a bit annoying, but since then the problem has been completely fixed and the anti-theft alarm system is working perfectly again, also thanks to the additional battery being fixed. So all in all, there's nothing major to worry about. I hope this helps and keep my fingers crossed that you get it fixed quickly and cheaply!

Hey, that reassures me a little. Of course it's annoying that the repair costs something, but if it runs smoothly afterwards, then it's worth the €235 to me. Thank you for your help and the information. I'll see if I can get the problem under control in the same way. Thanks again and have a nice day!

Dear all, I have a 2019 Citroen C3 model. I tried today to put it in front with wires ( dead battery) and the alarm started to go off without being able to turn it off. The car is second hand and the alarm is probably factory. (it goes off automatically when I lock the car). Thank you very much. Argyris Koutsoubis.

Check if the car battery is fully charged and in good condition, as a weak battery can trigger the alarm. If the battery is fine, inspect the alarm system's wiring and connections for any loose or corroded contacts. Let me know how it goes or if you have any further questions!

Hey, I had the same thing with my 2019 C3 diesel, mileage around 55000km. The siren suddenly started and wouldn't stop. After initially thinking it was due to the main battery being changed, it turned out it was actually the auxiliary battery in the siren. It's nothing major, but it can lead to confusion. The mechanic then checked the contacts and found that they were faulty. So he replaced the contacts of the anti-theft alarm system and that was that. Since then, everything has been running smoothly again. So, maybe it could be similar for you. Hope this helps you!
