How do I unlock my petrol cap?
Hold the cap that turns with one hand while you turn the key anti-clockwise with the other hand. Then, remove the key and then turn the cap anticlockwise and it will come off easily. It’s a two-handed job!
Why is My Audi gas cap not opening?
It could be dirty.
Remove the liner on the rear wheel that’s on the same side of the gas door, then locate the gas door locking mechanism. Once you remove the liner out of the way, you will see a small rubber piece that looks like a pencil eraser. Press on it and the gas door will open.
