Citroen C5 Hybrid Terminal 30 Interruption

Alright, Citroen gurus, I'm scratching my head here. My 2021 Citroen C5 hybrid is throwing a fit. Got about 146302 km on the clock. It starts poorly, and after some digging, it seems I'm having some kind of terminal 30 continuous plus interruption. I'm thinking power supply issue or voltage drop somewhere? Could it be the wiring harness, or maybe even a dodgy circuit breaker? Ignition switch perhaps? Anyone seen this before?

I had a similar issue with my C5, and the symptoms sound familiar. Was your battery heavily discharged by any chance? That played a role in my situation.

Interesting, so you reckon a discharged battery could cause that? Did you notice any other electrical gremlins before it got really bad? Thinking I should check for parasitic draw.

Yes, absolutely. I also experienced other electrical issues as well. Best to take it to the workshop and have them diagnose the battery properly. Replacing it solved my problems.

Thanks for the tip! Took it to the shop, turns out the battery was indeed heavily discharged and defective. New battery fitted, cost me 290€, and she's purring like a kitten again. Appreciate the help!
