Light problems and warning light on Citroën C3 Diesel model year 2009

Hey, I know it pretty well. I own a Citroën C5 from 2006 and had the same thing with the lights and warning lights, and it was actually the engine control unit. On my last visit to the garage, the engine control unit was faulty. This is a serious problem as it affects various vehicle systems. It's really annoying. In the end, the unit just had to be replaced. Don't wait too long to get it fixed, it could get worse. Hope this helps you. Take care of yourself!

Hey, thanks for the quick reply and the info. That's exactly what I was afraid of. Can you perhaps remember how much it cost you to replace the engine control unit? And were there any further problems after that or was that the end of the matter for you?

Hey, sure, no problem. So, it cost me a pretty hefty €1000 to repair the engine control unit. I know it sounds like a lot, but believe me, everything was back to normal afterwards. Interestingly, the software installed in the vehicle was also faulty, but the mechanic fixed it without any problems. Since then, everything has been really great again. So it helped me, and so far no further problems have occurred. So don't let it get you down. Keep your chin up, you can do it too!

Hey, thanks for your detailed reply. Of course it's annoying that the repair is so expensive, but I'm reassured to hear that everything was fine again afterwards. I probably won't be able to avoid taking the car to the garage. It really does seem that a new engine control unit is due. You've really helped me - I'll take your advice to heart and not let it get me down. Thanks again and take good care of yourself!
