Timing belt

Based on practical experience, recommended Volkswagen Polo 1.6 timing belt change interval is 200,000 km when belt should be replaced, or at least periodically check the belt's condition after this mileage and replace it at the first sign of damage.
Running your car in aggressive environments (e.g. salt, sand, etc.) causes timing belt to degrade faster and reduces its lifespan; under such conditions, the belt may need to be replaced sooner.
