How many kilometers should the spark plugs of the Touareg be replaced?
2 Answers
Volkswagen Touareg spark plugs should be replaced for the first time at 5,000 kilometers, and then every 20,000 kilometers thereafter. Below is the relevant information: Volkswagen Touareg Spark Plugs: The original factory uses NGK ZFR5EGP and Bosch Y7LER02 spark plugs. When replacing, open the hood, remove the engine panel, disconnect the steel wire, and use an extended socket to unscrew the old spark plug and install the new one. Before replacing the spark plugs, ensure the vehicle is turned off and cooled down before proceeding. Spark Plug Replacement Method: Disconnect the ignition coil harness plug, remove the ignition coil fixing bolts; inspect the spark plugs (check if the terminal is damaged, if the insulator is punctured, if the electrode is worn, etc.); select the appropriate tools, assemble the tools, remove the spark plugs, and take them out one by one; cover the spark plug holes on the cylinder with a clean cloth to prevent objects from entering the cylinder; align the ignition coil with the spark plug, install it in place, and use a tool to screw in the bolts; clean the measuring tool, measure the spark plug gap, and judge the spark plug; check the new spark plug for any appearance issues, place the spark plug into a dedicated socket, screw it into the spark plug hole using a digital torque wrench, tighten the spark plug, turn off the ignition switch, open the engine hood, and install the three-piece set; use a digital torque wrench to tighten. Start the vehicle, clear any faults, and tidy up the workstation.
I used to drive a Touareg for three to four years. Based on my experience, it's recommended to replace the spark plugs approximately every 60,000 kilometers. When my car reached 58,000 kilometers, I noticed the acceleration felt sluggish and the idle speed was unstable. After taking it to the repair shop, they found the spark plugs were severely worn. After replacing them, the car immediately ran much smoother, and fuel consumption also decreased. Don’t wait for a malfunction to replace them—prolonged neglect can lead to poor ignition, reduced engine efficiency, and may even affect other components. I suggest checking them every 50,000 kilometers to ensure safe driving.
