How often should the spark plugs of Volkswagen Touran be replaced?
2 Answers
Volkswagen Touran's spark plugs need to be replaced every 25,000 kilometers or 18 months. If the spark plugs are not replaced for a long time, it may cause various problems such as leakage in the vehicle's ignition system, increased fuel consumption, and decreased power. The most significant issue is difficulty in ignition, which affects the normal use of the vehicle. Spark plug replacement cycle: Under normal maintenance conditions, spark plugs should be replaced after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine, so it is recommended to follow the user manual. The following standards can be used as a reference for maintenance and replacement: platinum spark plugs should be replaced at 40,000 kilometers, ordinary nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers. Steps for replacing spark plugs: Open the hood, lift the plastic cover of the engine, and remove the high-voltage wires. Mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. When removing them, check for any leaves, dust, etc., on the outside and ensure they are cleaned thoroughly. Place the new spark plugs into the spark plug holes, hand-tighten them a few turns, and then use the socket to tighten them further. Reinstall the removed high-voltage wires according to the ignition sequence and secure the cover.
As a Touran owner for ten years, my previous model with the 1.6L engine required spark plug replacement every 30,000 km. After switching to the newer 1.4T version, the manual recommends changing them every 40,000 km. In practice, I make it a habit to inspect them every 2-3 years, as I've noticed that worn spark plugs can cause ignition issues, sluggish acceleration, and increased fuel consumption. Last time during replacement, the mechanic also reminded me that spark plugs in Volkswagen turbocharged models are more prone to carbon buildup, and delayed replacement may damage engine components. Now during every maintenance session, I proactively have professional shops check the spark plug condition—especially when doing frequent highway driving—to prevent sudden failures on the road. The Touran’s spacious interior is perfect for family trips, and this maintenance effort ensures safer travels.
