Peugeot 301 fuel flap issue

I had a similar issue with my Peugeot 301 (don't remember the year). From what you're describing, it sounds like a problem with the release mechanism for the fuel filler. Did you try checking the key fob? Some models have a dedicated button for the fuel flap. Also, can you provide more detail about 'some functions of the vehicle are not available'? Which functions precisely?

Thanks for the quick reply! The key fob button does nothing, unfortunately. And yeah, the 'some functions' bit is vague, I know. Basically, the central locking acts weird sometimes, and I think it's related. What exactly was the problem with your 301? Was it the lock actuator?

Confirmed. Based on your description and my experience, I strongly suspect it's the lock actuator or the linkage, as you mentioned. Considering you've already checked the key fob and are experiencing other electrical issues, it's beyond a simple DIY fix. You will need to get it to a workshop and have them diagnose it properly. I had to get mine replaced, and it wasn't cheap.

Thanks a lot for the insight! I suspected it was going to be a trip to the workshop. I went to the garage, and you were right; it was the lock actuator. 210€ later, and it's all sorted. Appreciate the help!
