🇦🇺 Australian Owner Case Study

Real case from Sydney Tiggo 7 Pro owner (June 2025):

"My 2024 Tiggo 7 Pro showed P0455 after refueling at a Ampol station. Dealer wanted $400 to diagnose the EVAP system. I just tightened the gas cap until it clicked 3 times, cleared the code with an OBD2 scanner — problem solved, $0 cost.The cap wasn't sealed properly."

Australia-specific insight: P0455 is common in Australia after refueling with the engine running (some Australian fuel stations have automatic shut-off that doesn't seal the cap properly). Always turn off the engine before refueling, and tighten the gas cap until it clicks 3 times.
