How Many Kilometers Should Volkswagen Spark Plugs Be Replaced?
1 Answers
Volkswagen original spark plugs should be replaced every 20,000 to 30,000 kilometers under normal conditions. For iridium or platinum spark plugs, replacement can be done every 60,000 to 80,000 kilometers. Steps to replace spark plugs: Open the hood, lift the plastic cover of the engine, remove the high-voltage distributor wires, and mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing, check for any external debris like leaves or dust and ensure they are cleaned thoroughly. Place the new spark plug into the spark plug hole, hand-tighten it a few turns, and then use the socket to tighten it further. Reinstall the high-voltage distributor wires according to the firing order and secure the cover. Effects of faulty spark plugs: Damaged spark plugs can directly cause issues such as electrical leakage in the vehicle's ignition system, increased fuel consumption, and reduced power. The most significant problem is difficulty in starting the engine, affecting the vehicle's normal operation. Severe spark plug erosion, such as scarring at the tip, damaged or melted electrodes, indicates that the spark plug is ruined and should be replaced. Symptoms of faulty spark plugs in a car: Damaged spark plugs may lead to the following issues: difficulty starting, reduced power, excessive exhaust emissions, and increased fuel consumption.
