How often should the spark plugs be replaced in a Volkswagen Lavida?

Volkswagen Lavida spark plugs should be replaced every 40,000 to 60,000 kilometers. Spark plug replacement interval: Under normal maintenance conditions, replacement is recommended at 40,000~60,000 kilometers. However, this may vary depending on the brand and engine type, so it's advisable to follow the owner's manual. The following standards can be referenced for maintenance replacement: platinum spark plugs should be replaced at 40,000 km, ordinary nickel alloy spark plugs at 20,000 km, and iridium spark plugs at 60,000-80,000 km. Spark plug replacement procedure: Open the hood, lift the engine's plastic cover, remove the high-voltage distributor wires (mark each cylinder's position to avoid confusion), and use a spark plug socket to remove the spark plugs one by one. During removal, check for external debris like leaves or dust and ensure thorough cleaning. Insert new spark plugs into the holes, hand-tighten them a few turns before using the socket wrench to secure. Reinstall the high-voltage distributor wires according to the firing order and reattach the cover.
When I drove the Volkswagen Lavida before, I specifically checked the maintenance manual and consulted the 4S店 technician. There's really no fixed standard for spark plug replacement. Volkswagen officially recommends inspection or replacement every 20,000 to 40,000 kilometers, but it actually depends on the spark plug material and driving conditions. For example, ordinary nickel alloy ones can last up to 30,000 kilometers, while premium ones like iridium can go up to 60,000 kilometers. I drive aggressively and often take the highway. At the 30,000-kilometer maintenance, I found the electrode gap had widened, so I promptly replaced them. Remember, sudden car shaking, poor acceleration, or a spike in fuel consumption are likely signs of spark plug issues. During regular maintenance, you can have them check the wear and tear. If the rubber sealing ring is aged and leaking, it should be addressed at the same time to avoid repeated disassembly. Genuine parts cost around a hundred yuan and aren't expensive, but don't skimp by buying inferior products—you risk cylinder damage and engine harm.
Last month, I just helped my younger brother replace the spark plugs for his Lavida. He drove nearly 40,000 kilometers before remembering this. Volkswagen models generally recommend inspection and replacement between 20,000 to 40,000 kilometers, but the specifics depend on the model. My car, equipped with NGK platinum spark plugs, lasted 5 years before needing a change, while a friend with the same model, who frequently drives short distances in congested urban areas, had severe carbon buildup on the spark plugs in just 2 years. If you experience difficulty starting the engine cold or notice black smoke from the exhaust pipe, it's usually a sign that the spark plugs are failing. The original manual actually explains this quite clearly—look under the 'Ignition System' section in the engine maintenance pages, as requirements may vary by year and version. It's advisable to decide based on your driving habits: delay replacement if you mostly drive on highways, but change them earlier if you often drive in stop-and-go traffic. Buying the parts yourself and having them replaced at a repair shop costs around 200 yuan, which is half the price of a dealership service.
