How long does a B47 timing chain last?
BMW does not specify a fixed replacement interval for timing chains. That’s because, unlike timing belts, chains are designed to last the lifetime of the engine — in theory. However, in reality, certain BMW engines are prone to premature wear or failure, meaning the chain may need replacement well before 100,000 miles. BMW has built a reputation for performance and engineering excellence, but certain models, including the BMW X1 (2013–2015), BMW X3 (2013–2017), and BMW 3 Series (2012–2015), have been known to experience timing chain issues—especially in vehicles equipped with the N20 engine.F30 3 Series with N20 Engine (2012-2015) The 2012-2015 320i and 328i models with the N20 engines were prone to durability problems (timing chain issues, oil leaks and turbo longevity).
