Fuel fill door works intermittently

[Robd]

Pcx150/2018
My fuel fill door doesn’t always open when pressing the control button
Any suggestions ?
Thanks

Once the door is open you should be able to see a latch holding device just under the plastic. Try some WD-40 on it. Sometimes that works. I have had to take my tunnel cover off a few times and clean the mechanism. Also, carry something small with you to help pry it open when it doesn't release. I carry a pocket knife. It just needs a little help sometimes. Remember, it is a mechanical device, operated by a cable, not an electronic device.

Jiggle the key as you press the button, sometimes the seat/fuel switch doesn't unlock properly.

Tap the fuel flap at the same time as operating the switch, my 2018 model does this, tried cleaning/lubricating but can be embarrassing at the pumps if it sticks. One of the few cheap and nasty things I’ve found with mine.

Jiggle the key as you press the button, sometimes the seat/fuel switch doesn't unlock properly.

And make sure the key is in the right position. It still catches me out sometimes.

Something flexible, like a "wire tie" will slide under the cover and depress the release lever just enough to release the cover. Is there some way to adjust the cable?

Not sure if you are in the US, but a new lock mechanism (LOCK ASSY., FUEL LID 64440-K35-V00) is only $3.72 on PartZilla if you find that you need a new one.
