Battery weakness and flickering lights in Citroen C5 from 2013

Dim or flickering lights

|

Weak battery when starting the engine

Hello everyone, I have a problem with my 2013 Citroen C5 gasoline engine (mileage: 113970 KM). When I start the engine, my battery drains a lot and the lights flicker or dim partially. Last time I was at the garage it wasn't a nice experience, so I wanted to do better this time and thought I'd ask here first. Could it be that my vehicle battery is severely discharged due to self-discharge? Has anyone here had similar experiences, either with the problem in general or specifically with the Citroen C5? And what advice did you get regarding the garage? Any information and tips would be appreciated. Thank you! Best regards.

Hello, I actually had a similar problem with my 2010 Citroen C4 Diesel. In my case, however, it was a defective control unit. All the symptoms you describe also occurred with my car. The ECU sometimes shows errors in relation to the lights and battery power and that was the case for me. It is a serious problem, but in my case the repair was relatively straightforward compared to other possible technical problems. The main thing is to get your car to the garage quickly. I hope this helps you. Greetings.

Hello and thank you for your reply. You said that you had the same problem with your Citroen. Do you happen to remember approximately how much the repair cost? Oh yes, and since you had it repaired - has anything else come up? Thanks in advance and best regards!

Hello, sure, I still remember the price. It cost around €600 to repair the defective control unit. But that was a while ago, so the cost might be a bit different now. Of course, it can also depend on where you go, which mechanic looks at it and how intensive the repair is. Since I've had this problem fixed, there has been no more drama with the car battery. It no longer self-discharges, so that's been a real blessing. Everything is going well so far and the old one is holding out - at least so far. I hope this helps you a little and wish you the best of luck with your car. Stay safe out there! Best regards!

Hello and thank you for your help! It's good to hear that your car hasn't had any further problems since the repair. Hhhm, €600 doesn't sound cheap, but compared to the many worries you can have with such a defect, it definitely seems worth the money to me. So, I'll take my Citroen C5 to the garage as soon as possible and see what happens. Your information was really helpful! Thanks again and always drive safely. Best regards!
