Problems with the anti-theft alarm system tilt sensor in the Peugeot 607 petrol engine built in 2007

Hi, your problem reminds me of a similar one I had with my Peugeot 607 Diesel (built in 2005). I'm not a professional myself, but I do have some experience with cars as I like to get my hands dirty. The alarm system in my car was malfunctioning and after some research I found out that the fault was in the sensor system for the alarm. I went to my local garage and they confirmed my suspicions. The repair cost me around 250 euros. It turned out that the tilt sensor of the alarm system was causing the problems. It could be similar with your Peugeot. Could you perhaps give more details about your problem? Model specific info or particular signs might help. Hope this helps you a bit and you get further with your problem.

Hey, thanks for your reply! So, I noticed a few days ago that the alarm on my Peugeot keeps going off for no reason. After observing this a few times, I took my car, which now has 77532 kilometers on it, to my garage. The mechanic said that it could be the anti-theft alarm system's tilt sensor, but he wasn't sure and wanted to take a closer look. The only problem is that the garage is so busy at the moment that I'll have to wait a few weeks before they can repair my car. So I wanted to see if I could perhaps solve the problem myself. Maybe someone here in the forum has had similar experiences and can give me tips on what I should look out for or how I can fix the problem. During my research, I saw that there are spare parts for the sensor. Would that perhaps be a solution? Greetings!

Hey, thanks for the details! I can really understand your frustration. It's really annoying when the alarm goes off all the time. It was very similar with my Peugeot, it would sometimes go off in the middle of the night and wake up the whole neighborhood. So, with my problem with the tilt sensor, it also took a while for the garage to have time to look at it. In the meantime, I tried to solve the problem myself. It is important that you are careful when working on the alarm system, as it is linked to the central locking system and you could cause problems if you do something wrong. But to come back to your question about the spare part for the sensor: Yes, there are spares available and they could certainly be a solution to your problem. On my Peugeot, I replaced the sensor myself. It was relatively easy and cost me about 100 euros for the spare part. I ordered the part online and then watched a Youtube video to know how to fit it. You'd just need to be sure you're ordering the right part. I would definitely recommend having a mechanic confirm the problem first before ordering parts and fitting them yourself. And if you don't feel confident or the problem persists, it might be better to wait for a mechanic. Better safe than sorry! I hope this helps you and you can solve the problem soon. Good luck and let me know if it works! Greetings!

Oh, thanks for the detailed information and support! It's good to know that I'm not the only one with this problem. I'll take your advice and be very careful when working on the alarm system. Your tip about the central locking is also very valuable, I might have overlooked it otherwise. I think I'll try the replacement part for the sensor, that seems like a good solution. It's also good to know that it's possible to replace the sensor yourself, I was worried it might be too complicated. Before I order the part, I will talk to my mechanic again and ask for his opinion. Even though I like working on my car myself, I'd rather play it safe and not break anything. Thanks again for your help! I'll keep you all posted and report back on how it went once I've replaced the part. See you then and best regards!
