What causes the malfunction of the Golf 7 fuel tank cover?
2 Answers
Golf 7 fuel tank cover malfunction may be due to issues with the spring leaf. Generally, after prolonged use, the spring leaf may lose its elasticity. In northern regions, it could also be caused by freezing. It is rarely due to a broken pull cable. You can try having one person pull the switch in the driver's compartment while another pulls the fuel tank cover from the outside to see if it can be opened. Here is additional information: Reasons why the fuel tank cover won't close: Sometimes, improper installation of the fuel tank cover may cause the outer cover to fail to close. The typical refueling procedure involves lifting the fuel tank switch, which opens the fuel tank cover located at the left rear of the vehicle, then slowly unscrewing the fuel tank cap and hanging it on the back of the fuel filler cap. When reattaching the fuel tank cap, turn it until you hear a click, and the cap will slightly rotate back when released.
My Golf 7 had this issue too—the fuel filler cap just wouldn't open no matter what. I figured it could be a few things: most commonly, the little solenoid lock behind the fuel cap that controls opening and closing might be broken. Or, the fuel cap spring could be worn out and not providing enough tension, causing it to jam. Another possibility is a loose or stuck release cable connection, or even mechanical parts freezing up in winter. I first tried pressing the remote key repeatedly and checked the emergency release handle on the left side of the trunk—turned out the solenoid lock was faulty. Replacing it with an OEM part fixed the problem. I’d suggest checking these spots first before forcing it open to avoid scratching the paint.
