Mazda 2 gas gauge indicator showing D interpretation issue on Mazda 2

Some Mazda 2 owners report experiencing issues with the gas gauge indicator, particularly a "D" interpretation problem, which may result from the fuel gauge not registering correctly unless more than approximately 9 liters of fuel are added. Dealerships suggest that these inaccurate readings could stem from a combination of the vehicle's large fuel reserve and driving habits, especially during long-distance motorway driving. Additionally, owners are advised to keep the fuel tank above 1/4 full to ensure accurate readings, as the indicator may fluctuate while driving on slopes or curves due to fuel movement. If the issue persists, some owners find it necessary to investigate common causes such as a loose fuel cap, excess vibration, a blocked cylinder, a bad fuel mix, excessive heat, or problems with transmission or engine oil levels. In cases where the problem continues, consulting an expert repairer, preferably an Authorized Mazda Repairer, is recommended for further diagnosis and resolution.
