What is the solution when the Golf fuel tank cover cannot be opened?

The solution when the Golf fuel tank cover cannot be opened is to replace the electronic valve. The fuel tank cover of the Golf is located on the right rear side of the car. Taking the 2021 Golf as an example, it belongs to the compact car category, with body dimensions of: length 4296mm, width 1788mm, height 1471mm, wheelbase 2636mm, fuel tank capacity 51L, and trunk capacity 380L. The 2021 Golf is equipped with a 1.2T turbocharged engine, with a maximum horsepower of 116PS, maximum power of 85kW, maximum torque of 200Nm, and is paired with a 7-speed dual-clutch transmission.

When I encounter the issue of a Golf fuel tank cap not opening, I always prefer to tinker with it myself first, as such minor problems are quite common. The most frequent causes are dust or mud stuck in the lock groove, combined with exposure to wind and rain which can lead to rust and cause the cap to stick. The solution? First, try gently turning the key to unlock it—don’t use too much force to avoid breaking the key. If it doesn’t turn, I’ll take a soft cloth, dip it in some lubricant (like WD-40), spray it around the lock groove, wait a few minutes for it to soak in, then lightly push the cap while turning the key. If that still doesn’t work, a plastic pry tool can be used to gently lift the edge, but avoid pulling hard to prevent damaging the paint. For prevention: regularly clean the cap and lock groove after refueling and apply some anti-rust oil to keep it lubricated. Remember, don’t get impatient in such situations—take your time to handle it. But if several attempts fail, it’s best to visit a car shop for inspection, as it might be due to internal lock wear or connection issues that require professional attention.

As a new driver, I panicked when I couldn't open the fuel tank cap of my Golf for the first time at a gas station. Later, a friend taught me simple steps: the issue is often caused by dust or small stones jamming the cap, or a frozen lock cylinder (common in winter). Solution: First, confirm the car is unlocked (some models link it to the anti-theft system), then gently tap the edge of the cap with your fingers to loosen any debris while trying to turn the key in the lock hole. If it's stuck too tight, spray some household lubricant or use warm water to melt ice before trying again. I later learned to regularly check the cleanliness of the cap and lock slot to prevent issues. If it doesn't work, don't force it to avoid damage—seek help from a nearby garage or call for assistance, safety first. Also, remember to wipe the cap after refueling in dusty areas and keep it lubricated to minimize problems.

I think solving the issue of a stuck fuel tank cap is quite simple. Common causes: the cap is jammed by dirt or the lock hole has rust. Solution: gently turn the key in the lock hole, if that doesn't work, add some engine oil for lubrication, then apply a bit more force to push the cap outward. Quick fix done!
