The pin should not be cut. It is meant to be used to hold the fuel cap while fueling.

You will find a small circular hole on the top of the fuel door arm. Insert the pin there while fueling the car.

For some reason, your replacement fuel cap is not the same as your original. My car has the same as your car originally had, but my GLE has the same one as your replacement.

 

Hello. Maybe it’s a model year difference? I have a 2023 GLA45 and my fuel cap has the pin. It does make it handy to hold the cap when fueling.

 

Sorry forgot to Clarify i have a 2016 Model so still the old one but according to Mercedes it should still be compatible

 

Sounds like you have the wrong model cap. Our 2017 45 has the tether that we hang over the hook on the fuel door to hold the cap away from the body when filling.

Could be just be a misreading/mistyping thing, but hanging by the tether? There’s an actual cut out in the hinge of the flap to fit the entire cap into, as can be seen on the pic posted above.

 

Yes but it dosent fit into the holder because of the pin i took a pic today

 

That cavity sure looks like the cap should fit in, but IMHO it doesn't fit securely. I did have it fall out once. It hit the fender causing no damage. But that was enough. I simply found it a lot quicker and more fool proof to hang it down. I do the same thing on my 997 (2010 911).

 

Ah I see. Mine sits all crooked and thus fell down and hit the fender because the top part is made from aluminum it made a small scratch I thought about leaving it hanging from the wire but I’m scared that overtime through wear and tear some scratches may appear since the pin is only for the newer models to hold it in and serves no Purpose otherwise I might just cut it off

That scratch has been bugging me for the past few days now

 

Odd. My 15 gla45, the gas door PN is A 222 470 02 50. Your PN is totally different. Wonder why they were listed as compatible

 

If you find that magic method you will never again find yourself wanting for money!!!!

Good luck with the repair.

Same here, it has that little stand up ear, I just take the plastic line and put it behind that and let it hang.

 

For Anyone Interested i cut the Pin on the Fuel Cap off and it fits perfectly now.
