The fuel tank cap of Golf 7 cannot be opened because the electronic valve of the fuel tank cap is damaged. Replacing the electronic valve can solve the problem. The following is extended information about Golf 7: 1. Press the central locking button of the car key to unlock the car inside. 2. The fuel tank cover is located on the right rear side of the car. 3. Press the rear end of the fuel tank cover to open it. 4. Rotate the fuel filler cap counterclockwise to remove it and hang it on the fuel tank cover. 5. Add fuel after turning off the engine, ignition switch, and mobile phone.
I've been driving for over ten years and often repair cars myself. The issue of the Golf 7 fuel tank cover not opening is quite common, possibly due to a stuck lock or freezing. First, check if the remote key unlocks the door locks effectively, as the fuel tank cover is usually linked to the door lock system. Try gently pushing or pulling the edge of the cover to loosen it. If it's caused by winter ice and snow, use a hairdryer to heat it but avoid high temperatures that could damage the paint. Spray some WD-40 to lubricate the lock pin area to prevent damage from forcing it. If that doesn't work, consider rust in the lock mechanism or an electronic fault—remove the inner lining to check the cable connections. The Golf 7's fuse is under the glove box; check if it's blown. Regular cleaning of the lock area can prevent issues. If you can't fix it yourself, go to a professional shop early to save time and hassle.
As a safety-conscious veteran driver, my first priority when encountering a fuel filler door that won't open is to avoid risks, such as rainwater or snow entering and damaging the engine. First, ensure the car is parked stably and the engine is turned off, then try the key unlock function several times. If there's no response, it might be a linkage failure or foreign object blockage—avoid forcing it to prevent scratching the paint or causing bigger issues. In winter, be mindful of freezing and wait for thawing. From personal experience, the Golf 7's electronic system occasionally has delays, so patiently press a few more times. If all else fails, promptly drive to a 4S shop for inspection—they can check for fuse or module issues to prevent recurrence. Maintenance costs aren't high, but safety is paramount.
