Good evening - we have a 2012 MB GLK350. As it turns out, like many other Mercedes models, it has a locking fuel door (why I am not too sure). The door is now stuck shut and we are just about out of gas. Youtube tells me that many MB models have a hand release to manually release the door. We have not been able to find one on this, and are having a lot of trouble trying to access the module itself as there is a very narrow passage behind the tail light and up to the back side of the fuel door. Has anyone encountered this? Please help.

There is a possibility that the pin receptacle that locks the filler door is out of alignment. Try applying slight pressure to the door while using the key fob to lock and unlock the the car. See if you can feel/hear the pin move.

It turns out the fuel door was likely just frozen. It opened on the way to getting it fixed. Hopefully that is the last of it, though I doubt it.

It may be too late but if it happens again, then perform this.

Thank you very much. Interestingly, ours does not have the red fail safe!
