Tiguan car fuel tank cap cannot be opened solution is as follows: 1. The Volkswagen Tiguan fuel tank cap can be unlocked via remote control. After unlocking the car, press the fuel tank cap door to open it. If the fuel tank cap still does not open, you can start from the trunk; 2. First, remove the trunk lining covering the fuel tank to expose the fuel tank cap locking mechanism. You will also see a remote-operated fuel tank cap cable. Simply pull the cable to open the fuel tank cap; 3. If this does not work, press the movable part of the locking mechanism while continuously pulling the cable. The fuel tank cap will then open easily. Some models have a dedicated switch on the locking mechanism—pressing this switch will open the fuel tank cap.
I've been driving an old Tiguan for over ten years and have encountered the issue of the fuel tank cap not opening. Common problems include the cable getting stuck or the locking mechanism failing. In the old Tiguan, the fuel tank cap is linked to the trunk, so first try checking the trunk unlock button. If that doesn't work, the cable might be broken or blocked by debris. In my case, the cable was corroded, and spraying some WD-40 lubricant into the lock hole helped loosen it. If you really can't open it, don't force it to avoid damaging the door or fuel tank opening—just take it to a repair shop to replace the cable, which costs only a few dozen yuan. Regular rust prevention maintenance is important; dry it promptly after rain to avoid rust. Another trick is to open the inner trim panel of the trunk and check if the cable connector is loose. Tightening it yourself can also solve the problem, saving you unnecessary expenses.
It's quite annoying when the fuel tank cap of the old Tiguan won't open. I just dealt with this issue last month. First step, after unlocking the car, don't rush. Gently press the edge of the fuel tank cap to see if it can be pushed open; sometimes mechanical jamming or foreign object blockage causes this. Second step, check the trunk button as it controls the fuel tank cap lock. If pressing it doesn't work, it might be a cable fault or electrical connection issue. I've tried gently tapping the lock position to help lubricate and loosen it, but don't use too much force. Third step, if it still won't open, don't risk damaging it—just drive to the repair shop. They can diagnose and fix it with professional tools, costing between 50 to 150 yuan. Regularly cleaning the lock groove during car washes can prevent such troubles.
