Hi, I have a 2015 Citroen DS3 and I had a similar problem with my battery. When starting, the battery also became weaker and the lights flickered. The garage found out that my battery was faulty. They had to replace my battery and check the electrical wiring. It wasn't a big deal, but it still took some time at the garage to check everything and make sure there weren't any other issues. All the best with your car! VG

Hi, thanks for the quick reply! It sounds like my problems could have similar causes. Do you remember how much you spent on changing the battery and checking the wiring? And have there been any other difficulties since then? Thanks again for your help! LG

Hello, I'm glad my answer was able to help you a little. Yes, I remember that the repair cost me about 290€. That was for the battery change and the whole wiring check. But you have to remember that the cost depends entirely on the damage and the individual workshop prices. Since the mechanic's visit, the problem with the overvoltage in the vehicle has been resolved. My battery is now running perfectly and I no longer have any problems with flickering or weak lights. Hopefully this will be the case for you too! Good luck and let us know how it goes! VG

Hello, thank you very much for the detailed information. That helps me a lot and reassures me a little. So I will make an appointment at the workshop next. 290 is a bit expensive, but if everything runs smoothly afterwards, it's worth it. I'll let you know how it goes. Thanks again for your help! LG
