2 Answers
The solution to the fuel cap of Golf 7 not opening is to replace the electronic valve. It is recommended to go to a 4S store or a professional auto repair shop for replacement in time. Golf 7 refers to the 7th generation product of Golf, with body dimensions of 4255 mm in length, 1799 mm in width, and 1452 mm in height. In terms of power, Golf 7 is equipped with three turbocharged engines: 1.2T, 1.4T, and 2.0T. The 1.2T engine has a maximum power of 81kw and a maximum torque of 200nm, matched with a 7-speed dual-clutch transmission. In terms of suspension, Golf 7 adopts a combination of front MacPherson independent suspension and rear torsion beam non-independent suspension.
When driving a Volkswagen Golf 7, I've encountered situations where the fuel cap wouldn't open, usually due to the lock cylinder getting stuck in cold or humid weather. First, make sure the car doors are unlocked since the fuel cap lock is connected to the door system. Try pressing the unlock button on the car key or the control button inside the car, then gently press the edge of the fuel cap to see if it loosens. If that doesn't work, I usually spray some WD-40 lubricant on the lock cylinder or apply a hot water bag to expand the parts, waiting patiently for a few minutes before trying again. Never force it open to avoid scratching the paint or damaging the lock mechanism. The Golf 7's fuel cap is designed to be quite tight, so remember to regularly clean off dust or grease during maintenance to prevent rust; in winter, it's best to wipe off moisture with a dry cloth. If you still can't manage it, drive to a 4S shop—they have specialized tools to handle it quickly. This common issue often occurs in older models or cars left unused for long periods. Proper use of lubricant can save a lot of trouble.
