What to Do When the Q3 Fuel Tank Cap Won't Open?

[DeMaria]

Audi Q3 fuel tank cap may not open due to it being stuck or rust on the hinges. Solution: You can insert a small wooden piece into the gap of the fuel tank cap to pry it open while simultaneously pulling the fuel tank cap's latch switch. Other reasons why the Audi Q3 fuel tank cap may not open include: 1. Fuel tank cap cable falling off: Open the trunk, and on the side of the fuel tank cap, there is usually an inner panel that can be opened, secured by a few plastic clips. Once opened, you will see the long cable operating the fuel tank cap; just pull it. If this doesn't work, try moving the movable parts of the locking mechanism while pulling the cable. 2. Loss of elasticity in the fuel tank cap spring: You can add a small spring (not too soft or long) to the protruding rubber pad of the fuel tank to increase elasticity between the cap and the locking device. 3. Aging of the fuel tank cap's engagement area: Apply lubricating grease to the hinges and engagement area of the fuel tank cap for lubrication.
