Reasons why the fuel tank cap of Volkswagen Tiguan L cannot be opened: Wire or motor issue: Some car fuel tank caps come with a locking motor, while others use a wire. If it's a wire, you need to check if the wire is broken. If it's a motor, you need to check if the motor is functioning properly. Incorrect method of opening the fuel tank cap: Car fuel tank caps are divided into inner and outer caps. The inner cap is the sealing cap of the fuel tank and can be opened by turning it counterclockwise. The outer cap is an anti-theft cap, which may have a lock or a mechanism lock. If it has a lock, it can only be opened with a key. If you still can't open it, it is likely that the wire of the fuel tank cap is faulty, and you will have to go to a 4S store for inspection and repair.
I had this happen to me last time—pressed the fuel filler cap but nothing happened, just heard a clicking sound but it wouldn't pop open. Most likely, the small spring got stuck or the release cable got bent. German cars love these mechanical cable designs—just peel back the carpet on the left side of the trunk to see the cable, then give it a tug to see if it loosens. If it's frozen, it's even more annoying—just pour some warm water to thaw it. Also, if the fuel filler flap is warped, it can jam too—try pushing the edges of the cap. For older cars, check the latch more often—my coworker's car had a latch that rusted shut. In an emergency, there's a release handle inside the right-side trunk liner—just pull the small yellow-tagged vertical handle and it opens super easily. Remember to ask the mechanic to apply some grease to the latch during maintenance.
