How to refuel when your car's fuel cap won't open: A handy guide

In the past, fuel fillers were usually not secured or had locks that could be opened with a key. Today, technology has advanced, and in most modern cars, the fuel filler begins with a button inside the vehicle, usually near the driver's seat. Unfortunately, this modern solution has its drawbacks. It may happen that the electronic fuel filler opening system doesn't work. This is precisely when the red cord in the boot comes in handy.

The red cord mentioned is standard equipment in newer cars, where the fuel filler is opened by a button. The flap is unlocked thanks to an electronic actuator. Unfortunately, this mechanism sometimes stops functioning. This can be caused by wear and tear (often after several years, when the driver does not maintain the cleanliness of the actuator) or frost (when accumulating water freezes and blocks the actuator).

In such a situation, you don't need to go to a mechanic or call a tow truck immediately. Just check the boot, find the red cord, and manually open the fuel filler, allowing you to refuel the car.

The red cord is hidden in the boot. Many drivers don't even know it exists until they need to use it. It is usually located in the side wall on the same side as the fuel filler flap. You need to look for it under a soundproofing layer. Sometimes, it may also be secured with a plastic cover. Just remove it and pull the cord to open the filler flap emergency.

It's worth noting that the red cord in the boot is intended solely for emergency situations. Remember, if the actuator wears out, you won't be able to keep using this method. Depending on the car model, a new actuator can cost from several dozen to about £20, and adding labour costs, the total replacement cost will be around £40.
