Vehicles using IQDA engine list:

Engine IQDA commonly faces issues such as timing chain wear, oil consumption, and occasional misfires. For diagnosis, listen for rattling noises at startup indicating timing chain tensioner problems. Regularly check oil levels and quality to prevent sludge buildup, which can cause misfires and reduce engine life. Preventive maintenance includes timely oil changes with manufacturer-recommended grades and inspecting the timing chain and tensioner around 100,000 km. Solutions involve replacing the timing chain kit if stretched or damaged and addressing oil leaks promptly. Keeping the ignition system and fuel injectors clean helps avoid misfires, ensuring smooth engine performance and longevity.
