I’m not a G07 owner, just lurking around and found this thread. There is a PuMA measure for this so I’m attaching it here for you guys. The dealer should take care of this under warranty as it is a known issue. Hope this helps you guys...

PuMA measure
Fuel tank filler flap sticking
65308294-01 - 29/01/20

Complaint:
It is no longer possible to easily open the fuel tank filler flap by activating the PushPush function.
The opening force of the fuel tank filler flap is significantly increased or the fuel tank filler flap gets stuck.

Cause
The plastic material for the hinge arm absorbs water and under certain ambient conditions (high air humidity) can become deformed so that the designed fit between the individual components is no longer present.
This deformation is reversible if the component is dried sufficiently.

Measure
1. Remove the fuel tank filler flap (image 1) and check the white label on the hinge arm (image 2).
If the last two numbers of the above number (see mark in image 2) are less than 10, continue with step 2.
If the last two numbers are greater than or equal to 10, this service solution is not relevant.

2. Check the hinge arm is opening correctly by pressing on the ejector area (see mark in image 3).

3. Open the hinge arm and top centering support flush (image 4) with the aid of a sensor gauge (image 5).

4. Reduce the value measured by the sensor gauge by 0.7 mm, set the reduced height on the sensor gauge, place on the top centering support (image 6) and file off flush (image 7).

5. Close the hinge arm. The distance between the hinge arm and the housing (image 8) when closed should be at least 0.1 mm.

6. Blacken and polish (image 10) the filed centering surface (image 9).

7. Open the hinge arm. Measure the aperture for mounting of the ejector (mark in image 11) with a caliper gauge at the inner distance (image 12).

8. Enlarge the inner distance of the aperture by 1 mm by filing the inner support edge (image 13 and mark in image 14) without wearing away the ejector centre support (image 15).

9. Check the distance with another measurement (image 16) and compare with the previous measurement (step 7).

10. Place the fuel tank filler flap with the back of the fuel flap facing upwards on a non-scratch surface (image 17).
Place butyl tape (image 18) approximately 5 mm in length on the contact surfaces of the hinge arm (see mark in image 19) (image 20).
Repeat the step for the lower contact surfaces (image 21) (image 22).

11. Mount the fuel tank filler flap on the hinge arm and close.

Invoicing:
Processing and reimbursement must be conducted according to current warranty conditions.
