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. We often see timing chains needing replacement at 60,000 miles onwards.
We offer timing chain inspection and replacement services using OEM or upgraded components for most BMW petrol and diesel engines.
Our experienced technicians follow BMW’s exact procedures, ensuring your engine is timed perfectly and runs like new.
