Citroen C5 fuel flap issue

Greetings. Your predicament seems familiar. I encountered a similar problem on my 2018 Volvo V60; the fuel door would not release, accompanied by an error notification. In my case, the issue stemmed from a malfunctioning lock actuator. Does the error message provide any specific diagnostic trouble codes?

Thanks for the quick reply. No specific codes, just a general error regarding vehicle systems. How did you eventually resolve the issue with your Volvo?

In my particular instance, the root cause was indeed the fuel door lock actuator. I recommend you take your vehicle to a qualified workshop for thorough diagnostics. Given the symptoms you described and the error messages, there's a high probability that a faulty actuator or a defective linkage is preventing the fuel door from releasing. I think you would be best served by having it checked over by a professional.

Thanks, I appreciate the advice. I took it to the workshop, and you were spot on! It was indeed the fuel flap lock actuator. The repair cost 210€. At least it's sorted now!
