How to Solve the Popping Sound in the Mondeo Fuel Tank?
2 Answers
To solve the popping sound in the Mondeo fuel tank: 1. Check if the carbon canister is clogged, causing excessive negative pressure in the fuel tank, and clean the carbon canister; 2. Replace the carbon canister. Taking the 2020 Ford Mondeo as an example, it is a mid-size car with body dimensions of 4873mm in length, 1852mm in width, and 1470mm in height, with a wheelbase of 2850mm and a curb weight of 1592kg. The 2020 Ford Mondeo is equipped with a 1.5T turbocharged engine, delivering a maximum horsepower of 182PS, a maximum torque of 243Nm, and a maximum power of 134kW, paired with a 6-speed automatic transmission.
I've been driving a Mondeo for several years and have encountered the fuel tank popping sound issue a few times, usually caused by pressure imbalance. The reasons could be a clogged charcoal canister or a loose fuel tank cap, which creates noise when gas expands. I've personally checked it myself: first tighten the fuel cap and drive for a few days to test. If the sound persists, you can order a new charcoal canister online and replace it—the steps are simple, just remove the old canister and install the new one, ensuring it's sealed properly. Also, avoid filling the tank completely when refueling; leave some space for gas expansion to prevent the issue. Additionally, regularly check the vehicle's ventilation system and clean out any debris to avoid blockages. If you're not familiar with the process, visiting a 4S shop or professional repair shop is a hassle-free and safe option.
