I had the same problem on my Opel Corsa GSi (5 door model) - all doors unlocked but the electronically controlled petrol flap stayed locked. To fix it open rear door -remove small plastic cover seen under right hand shelf. reach in (difficult) and you will feel the control relay for the petrol flap - move it around whilst operating the remote control - you will feel the relay operating - eventually the petrol flap will open. add lubricating oil to the pin that you will see once the petrol flap opens - hopes this helps.
There is know release button on the corsa c, all you do is unlock the whole car which then unlocks the petrol flap then you can pull it open with your hand.
how do I fit a petrol flap to a vauxhall meriva
car doors must be unlocked then pull petrol flap
On the Corsa C model (2000-2006) it's located to the right-hand side of the windscreen washer reservoir, under a flap.
To open the filler cap, you press the cover and it should open (with the car unlocked). To close it, you press it down again until it clicks. Sometimes the flap stays open. Move the red plastic tag, holding the actual fuel cap, as this can stop the flap from closing.
Hi - dont think there is a release button as such , however , if you push the door open button on the key fob it should release all locking including flap and rear doors. Cheers Andy
Push the right hand side of it inwards.
You need the vehicle unlocked to open the fuel flap. The central locking also locks the fuel flap on this model.
push on the right side should flip open
check under the outside edge of the drivers seat.
hi jack up the rear of the car remove wheel remove wheel arch covers. you will then see the two 8mm nuts holding the petrol flap a bit tricky for access but possible . kind regards mark mechanic
Hi turn the wheels on full lock there is a flap in the wheel arch you access the head light bulbs there.
