Citroen C1: Weak battery, flickering lights and stuttering engine - possible generator damage?
(Translated from German)
Summary of the thread
A 2008 Citroen C1 is experiencing issues with a weak battery, flickering lights, and a stuttering engine, leading to suspicions of alternator damage. However, a similar case with a Citroen C3 revealed that a defective engine control unit could cause these symptoms. Replacing the engine control unit resolved the issues in the C3, suggesting it might be a viable solution for the C1 as well.

Hey, great that you're sharing your experience with us! During my last visit to the mechanic, I was also skeptical as to whether it might be the engine control unit - you confirmed my suspicion. This may sound silly, but do you remember how much the repair cost you? And did anything happen again afterwards or has your C3 been running problem-free since then? Thank you in advance for your help!

Hey, sure, no problem, I'm happy to share my experience! So, the repair cost me €1000 to fix the broken engine control unit. It's not exactly small money, of course, but since then the car has run like clockwork. And the problem with the alternator? A thing of the past! Since the visit to the mechanic, the thing hasn't reported back. So, cheer up, your Citroen C1 is sure to be fit again!

Hey, thanks for the quick reply and the useful information! Now I feel a bit better and have more clarity. It does cost a lot of money, but if it stays that way, I think it's justifiable. It's also good to hear that your alternator hasn't made a noise since then. That gives me hope for my Citroen C1! I'll ask my mechanic about it soon. Thanks again for the help, man!

Hey, I had a similar problem with my 2005 Citroen C3 (gasoline) and it turned out that the engine control unit was defective. It was definitely a serious problem because the engine control unit is the brain of the engine, so to speak. The symptoms you describe partly fit this picture. On my last visit to the garage, the engine control unit was replaced and since then my old C3 has been running like clockwork. So remember, it could be the engine control unit. It's a good idea to check this first. Hope this helps you! Good luck.
