Problems with the electrics and battery in a 2014 diesel Citroen C1: Possible causes and solutions

Hey guys! Have any of you had problems with a 2014 diesel Citroen C1? Lately my electrics have been acting up, have fault codes, my lights are dimming or flickering and the battery is low when starting. I'm wondering whether a break in terminal 30 could be the cause. Have any of you had similar experiences or had something similar fixed in the workshop? Thank you for any tips or experience you can share!

Hi, I have been going through similar difficulties with my 2012 gasoline Citroen C3. I have some experience with cars because they are my main interest. When the electrics in my car went haywire, I went to the garage. It turned out that the problem was actually with the electrical system control unit. It was faulty and had to be replaced. It cost me 1000 euros, but after that my car ran smoothly again. Before I give you more specific advice, it would be helpful if you could give me a little more information about your vehicle. For example, how old is the battery? Is it perhaps a few years old and could need replacing? Hope this helps you a little!

Hello and thanks for the quick reply! The battery is actually a bit older, but I had it checked last year and everything was fine. The car now has 30538 km on it and the last service was a good 6 months ago. Maybe I really should have the electrical system control unit checked. Thanks for the tip!

Hi, great that you replied so quickly! So if the battery has already been checked and is OK, then that's good news. Given the mileage and the age of the vehicle, it could well be that something is wrong with the electrics. In my C3, as already mentioned, it was the electrical system control unit. It could also be possible that the problem is coming from terminal 30, as you originally suspected. These things can corrode or become loose over time and cause this type of fault. It might be a good idea to have this checked when you take your C1 to the garage. Hope this helps you!

Hello, your answer really helps! Corrosion at terminal 30 would indeed be possible, I hadn't even thought of that! I will definitely have it checked. And if the problem can't be fixed, I'll take a closer look at the on-board control unit. I really appreciate your helpful tips, thank you! I'll keep you up to date! See you then!
