In general, BMW timing chains in the 3 Series are designed to last the lifetime of the engine and typically do not require replacement under normal conditions. However, issues can arise due to wear, especially in older models or those with poor maintenance history. It's essential to monitor for any signs of chain noise or engine performance issues, as these could indicate a problem. Regular maintenance and inspections can help ensure the timing chain remains in good condition.
