How often should the timing chain of Volkswagen Lavida be replaced?

Generally, the timing chain should be inspected after driving for seven or eight years or around 100,000 kilometers, and the replacement cycle is approximately between 150,000 to 200,000 kilometers. The exact timing depends on the actual usage of the vehicle. Timing Chain: The main function of the timing chain is to drive the engine's valve train, ensuring that the intake and exhaust valves open or close at the appropriate times to allow the engine cylinders to intake and exhaust normally. Compared to traditional belt drives, chain drives are more reliable and durable. Consequences of not replacing it in time: The chain may gradually stretch, which could lead to valve interference, resulting in unstable engine operation, poor acceleration, or even skipped teeth causing engine failure.
Last time during maintenance, the mechanic mentioned something about the Lavida's timing chain. The manufacturer claims it's maintenance-free for life, but you'd be a fool to take that at face value. My neighbor's car, which has clocked nearly 160,000 km, rattles like a tractor during cold starts. When they took it in for repairs, they found the chain had stretched significantly. The mechanic said cars that mostly do short urban trips are harder on the chain, and recommended checking the tensioner around 120,000 km. If you hear metal grinding noises from the engine bay or the check engine light suddenly comes on, don't hesitate—get the chain inspected immediately. Replacing it with an OEM part costs over 2,000 yuan including labor, but that's still better than having to overhaul the engine due to valve damage.
