Problems with the electrics and battery in the Citroen Ccrosser model year 2009 - Possible interruption of terminal 15?

Hi, I can relate to this because I had a similar problem with my 2007 Citroen C4 Coupé. I would describe myself as someone with little knowledge of cars. My car showed similar symptoms and the diagnosis was that the engine control unit was faulty. This was quite a shock as it is a complex part, especially if the car is older. I then contacted my garage. They actually confirmed the problem and replaced the engine control unit. The cost was around 1000 euros. It was expensive fun, but it fixed the problem. In order to be able to help you further, I need more vehicle information such as the exact model variant, the problem behavior and what steps you have taken so far to diagnose the problem. Where exactly do the electrical problems occur and under what conditions? The more information I have, the better I may be able to help you.

Hi, thanks for your help! My Ccrosser is the Exclusive version with all-wheel drive. The problems tend to be intermittent and intermittent. Sometimes when driving, sometimes directly when starting, both cold and warm starts. There doesn't seem to be a clear pattern. I haven't really started with the diagnosis yet, as I wanted to get advice first. I was once told that the contacts of the fuses should be checked, there could be moisture or dirt. My car has now covered 98544 km and was recently serviced in a smaller workshop. Thanks for your tip, I'll take it into consideration and have it checked out. Has your car done similar kilometers?

Hello again! I'm glad that my answer was able to help you. My Citroen C4 Coupé has around 90000 km on the clock, so it's similar to yours. Yes, moisture or dirt could definitely play a role and it would certainly not be wrong to check the fuse contacts. But if you're already talking about a fault with terminal 15, then perhaps you could also check the battery or have it checked. Sometimes it's just crazy battery phenomena that lead to such problems. In any case, you should get to the bottom of it, because in the long run this constant light flickering and the weak battery when starting can be quite annoying and may even damage the electronics. So, it's best to go to the workshop straight away and have it checked. Good luck with that!

Hello, thank you for the advice! I've actually already thought about having the battery checked. I will definitely do that before I take the car to the garage. It's certainly better to consider several causes. And you're right, the constant light flickering and the low battery are really annoying. Hopefully I can solve the problem soon. Thanks again for the tips, I will definitely look into the battery issue. It's really helpful to hear opinions from others who have had similar experiences.
