How often should the spark plugs of Volkswagen Touran be replaced?
2 Answers
Volkswagen Touran 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 issues such as leakage in the vehicle's ignition system, increased fuel consumption, reduced power, and most importantly, difficulty in ignition, affecting 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 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 to replace 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 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 distributor wires in the correct firing order and secure the cover back in place.
I've been driving my Volkswagen Touran for over five years. The general replacement interval for spark plugs is around 30,000 kilometers, but it really depends on how you use the car. Standard copper-core spark plugs typically need replacement at about 20,000 kilometers, while long-life platinum or iridium ones can last over 50,000 kilometers. Driving habits make a big difference: if you often drive on highways or experience less urban congestion, spark plug wear is slower; conversely, frequent hard acceleration or short trips lead to much faster carbon buildup. After my last replacement, the car started quicker, the engine ran smoother, and fuel consumption dropped from 8L to 7.5L. The Volkswagen manual recommends checking them during every service - I regularly have my mechanic test them. Neglecting replacement can cause unstable ignition, increasing fuel consumption and emissions, and in severe cases, difficulty starting. Always choose genuine spark plugs for optimal compatibility. Proper maintenance helps a car last longer with fewer worries.
