The 2012 Volkswagen GTI has a timing chain instead of a timing belt. Unlike belts, timing chains typically do not require replacement unless they completely fail, which is not a common occurrence. Belts need to be changed out more frequently because they are external to the engine and vulnerable, while chains are internally located and receive lubrication from engine oil, which helps prolong their lifespan. If oil changes are neglected, the timing chain may wear out prematurely and need replacement. To assess the condition of the timing chain, check its tension and inspect the sprockets.
