Dear customer, I am sorry to hear that you are experiencing problems with the fuel inhibitor in your Audi Q7. The fuel inhibitor is a device that prevents a hose or foreign object from being inserted into the fuel tank to prevent theft or sabotage. Normally, the inhibitor opens when the petrol pump is inserted, but sometimes it can get stuck and prevent refuelling.
Simply put, there are some possible solutions to this problem:
You can try using an anti-seize product such as WD40 to lubricate the inhibitor cylinder and make it easier to open. Apply a little product and wait a few minutes for it to take effect, then try inserting the dispenser again.
You can try pressing lightly on the inhibitor with a screwdriver or spanner to release it. Be careful not to damage the device or the reservoir with sharp or pointed objects.
You can try to disassemble the jammer and clean it or replace it with a new one. To do this, you will need to access the fuel tank from underneath the car and disconnect the cables and hoses leading to the jammer. You may need special tools and technical knowledge to perform this operation, so let me know if you have any questions
