Understanding BMW Timing Chains: Durability, Reliability and Maintenance

At The Car Edition, our recent social media video on a BMW 530D timing chain replacement has sparked a lot of interest. Due to a high volume of enquiries, we are here to educate you about BMW timing chains, clarify their lifespan and reliability, and assure you of our expertise in handling these components across all BMW models.

How Long Do Timing Chains Last and Are They Reliable?

BMW timing chains are designed to last, typically enduring between 150,000 to 200,000 miles when the car is well-maintained. While timing chains are generally more durable and reliable than timing belts, they are not infallible and should not be considered ‘lifetime’ components as often marketed. They require regular checks, especially as the mileage climbs.

Signs Your Timing Chain May Need Replacement

Wondering if your BMW’s timing chain is due for a check or replacement? Here are some signs to watch for:

• Rattling noises from the engine, particularly when starting up.
• The engine runs poorly or misfires.
• The presence of metal shavings in the engine oil, indicating chain wear.
• Illuminated check engine light, which can be triggered by sensor failures related to chain slack.

Why and When Do Timing Chains Fail?

The main reasons for BMW timing chain failures include:

• Lack of regular maintenance, such as infrequent oil changes.
• Using the wrong type of oil, affecting the chain’s lubrication.
• Normal wear and tear, especially in high-mileage vehicles.

Specific BMW models, particularly those with the N47 engine (produced between 2007 and 2013) and N20/N26 engines (used from 2012 to 2015), are known for timing chain issues. Models like certain 1 Series, 3 Series, and 5 Series during these years have been affected more frequently.

Cost and Recalls

Replacing a BMW timing chain can cost between £1,200 to £4,000, depending on the model and the repair’s complexity. BMW has issued recalls and extended warranties for specific models due to widespread timing chain issues, particularly affecting the N20 and N26 engines. It’s worthwhile to check if your vehicle falls under these recalls for potential coverage.
