Seat Toledo fuel flap issue

That sounds frustrating. I had a similar issue with my Toledo, though I don't remember the exact error code. The fuel flap wouldn't open, which was a pain when I needed to fill up. Have you tried using the key fob to unlock the car multiple times in a row? Sometimes that worked for me temporarily. Also, does your release button make any sound when you press it?

So, when you say similar, do you mean the release button inside the car didn't work either? Did you also have other weird electrical issues at the same time, or was it just the fuel flap? Because right now, other systems are acting up too. What was the fix in your case?

Yes, the release button inside the car was completely dead, just like you're describing. I didn't have other electrical issues at the time, only the fuel flap. Given that you have other systems acting up, it does sound a bit more complicated. I tried a few things myself, but in the end, I had to take it to a workshop. They replaced some part of the locking mechanism, I think. Honestly, save yourself the headache and get it checked out by a professional. It's probably not something you can easily fix yourself.

Took it to the workshop, and you were right. They said it was a defective linkage. 210€ later, the fuel flap now opens perfectly, and the error is gone. Thanks for your help!
