How Often Should Volkswagen Spark Plugs Be Replaced?
1 Answers
Under normal conditions, Volkswagen's original spark plugs should be replaced every 20,000 to 30,000 kilometers. For iridium or platinum spark plugs, replacement can be done every 60,000 to 80,000 kilometers. Steps for replacing spark plugs: Open the hood, lift the engine's plastic cover, 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 them, check for any external debris like leaves or dust and ensure they are thoroughly cleaned. Place the new spark plug into the spark plug hole, hand-tighten it a few turns, and then use the socket to fully tighten it. Reinstall the high-voltage distributor wires in the correct 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 starting the engine, which affects normal vehicle operation. Severe spark plug erosion, blistering at the tip, damaged or melted electrodes, or burn marks indicate that the spark plug is damaged 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.
