How Often Should Volkswagen Replace Spark Plugs?
2 Answers
Volkswagen recommends replacing spark plugs approximately every 30,000 to 40,000 kilometers, generally in accordance with the maintenance manual requirements. However, delayed replacement of spark plugs may affect the vehicle's power and lead to increased fuel consumption. Spark plugs, commonly known as igniters, function by discharging the high-voltage pulses delivered by the ignition cables, creating an electric spark that ignites the air-fuel mixture in the cylinder by breaking down the air between the two electrodes. The Lamando, a compact car introduced by SAIC Volkswagen, features a front MacPherson strut independent suspension and a rear multi-link independent suspension. In terms of body dimensions, it measures 4615mm in length, 1826mm in width, and 1425mm in height, with a wheelbase of 2656mm. Power is provided by a 1.4L turbocharged engine, paired with a 7-speed dual-clutch transmission.
I remember when driving a Volkswagen, the spark plug replacement interval was quite flexible, mainly depending on your model and driving habits. My old Touran ran for almost ten years, and the manual suggested checking every 40,000 kilometers, but in practice, I usually replaced them every 5 years or 80,000 kilometers since I mostly drove in the city for commuting, which wasn't too demanding. If you frequently drive on highways or in poor road conditions, the spark plugs wear out faster, and you might need to replace them every 3 years. The key point is that neglecting replacement can easily lead to engine shaking and a sharp increase in fuel consumption. Once, I delayed it too long, and the car had trouble starting. Regular checks are simple—just open the engine hood, pull out the spark plugs, and see if there's carbon buildup or signs of burning. If they're too black, replace them immediately. Newer models now use platinum or iridium spark plugs, which are more durable and can last up to 100,000 kilometers, but don't skimp on this expense since it affects vehicle performance. In short, the maintenance manual is the gold standard—don't guess blindly; adjust according to your car's condition.
