Fuel Filler Door Peculiarity

I have noticed with my F33, that if the vehicle is locked and someone depresses the fuel filler door, it doesn't open all the way, but it does open a little further than the closed position.

Then when I get in and start the car, the fuel filler door opens even further and it is easy not to notice that the door is open. So, if someone should accidentally or intentionally depress the filler door walking by, and I get in to the driver's side of the car and start the car, my fuel filter door will now be pretty much open, even if I lock the vehicle.

Can anyone confirm this peculiarity?

I've noticed the same thing on my F 34.

Thanks. Seems like they should have disabled that first detente when the vehicle is locked. It has already happened to me more than once and it wouldn't be so bad if the car notified you that it was open.

To OP, the fuel door is held with a latch pin that is engaged by locking the car.

At the same time, the door has a toggle mechanism for "OPEN" and "CLOSE"

When the car is locked, the door can be pushed once and toggled to "OPEN", but the latch pin still holds the door.

When the car is unlocked, the latch pin will disengage hence the fuel door pops open.

My usual habit is to take a quick glance to see if fuel door is ajar or not while walking up to the car.

Yes. That is exactly how it plays out. I guess I just don't think it should have to be that way. I have had other cars where this was not an issue, even with a similar fuel door release.

The fuel door is locked when the car is locked. If you press it, you are releasing it from the spring loaded mechanism to push it out--but the lock is still in place. So when you unlock the car, the spring pops the cover out.

It's working normally.

Just because it is working normally does not mean it's right. I had a recent model VW with the same setup and the fuel door was never sitting there unlocked at it does in this scenario after unsecuring the car.

Yes, once you know how it behaves you can account for it, but I should think they could implement a solution where the door does not toggle open at all without the key.

Other cars probably have basic spring load hinge mechanism that open/close without push-to-toggle. My recollection is that my old E39 does not have such push-to-toggle feature for its fuel door.

Or, at the least, give you a message that fuel filler door is OPEN !
