How many miles to replace timing chain N57?
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. There is no service schedule for replacing the timing chain, it’s ‘Lifetime’ however is on average around 100,000 miles but that will be heavily dependant on how the car has been maintained from new, we have seen instances of snapped timing chains from 50,000 miles so it is something we strongly recommend you plan to .There is no service schedule for replacing the timing chain, it’s ‘Lifetime’ however is on average around 100,000 miles but that will be heavily dependant on how the car has been maintained from new, we have seen instances of snapped timing chains from 50,000 miles so it is something we strongly recommend you plan to .The average cost for a Timing Chain Replacement is between $2,061 and $2,683.
