How to Replace the Fuel Tank Cap on a Tiguan?

[OliveRose]

Tiguan fuel tank cap replacement method: 1. Soak the plastic shell part of the fuel tank cap in boiling water for a while, then use a flat-head screwdriver to pry it open along the junction between the plastic shell and the metal part (it's easier to pry after soaking in boiling water). 2. After prying open the plastic shell, pull out the lock core and plastic lock core slot from the metal shell (the lock core and lock core slot are still together at this point and not separated). 3. Insert the key into the lock core, then at the bottom of the lock core slot, there is a wire clip. After pulling out the clip, the lock core can be removed. If the key is not inserted, the lock core will scatter when removed, making reassembly more troublesome. 4. Install the new fuel tank cap, following the reverse order for installation.
