From 2009 to 2023, all BMW X1 models have timing chains instead of belts. In fact, all engines of the BMW X1 have chain-driven crankshafts. Due to their long-lasting and durable nature, BMW uses timing chains in their modern vehicles. As for timing belts, they are more likely to wear out over time.
Are you considering purchasing a BMW X1 but have heard conflicting information about whether it has a timing belt or timing chain? Or have you already got an X1, and your mechanic just told you about this belt or chain thing? Look no further! Let me explain.
So, today I’ll be talking about, Does Bmw X1 Have Timing Belt Or Chain?
Let’s start by unraveling the mystery of the BMW X1 timing belt versus the timing chain.

*The cost ranges refer to the buying cost of the timing chains and may vary.
From the above tables, you can see that all the models of BMW X1 from 2009 to 2023 are equipped with timing chains instead of timing belts. The genuine OEM equipment numbers vary depending on the engine model and type.
Additionally, if you ride a VW Polo, know whether it comes with a timing belt or a chain from this page.
[Note: Some engine models may contain both primary and secondary timing chains, also known as upper and lower timing chains. Lower timing chains have different OEM part numbers, so always check the owner’s manual before performing maintenance.]
Why Does the BMW X1 Have Timing Chains and Not Belts?
The BMW X1 uses a timing chain instead of a timing belt because it is more durable and reliable. Timing chains are made from metal and designed to last for the engine’s life, while timing belts are made from rubber and must be replaced every few years.
Timing chains are also more accurate than belts, which helps the BMW X1’s engine run more efficiently and smoothly. Another benefit of the timing chain is that it comes with a silent chain option. This minimizes engine noise for luxury vehicles.
Furthermore, The timing chain also requires less maintenance than a belt, which helps keep the engine running smoothly and reliably for years to come. These are the reasons why the BMW X1 series are equipped with timing chains instead of timing belts.
Summary:
The BMW X1 uses a timing chain instead of a timing belt because it is more durable, reliable, and requires less maintenance.
Which Timing Chain Does the BMW X1 Have?
The BMW X1 has a single-row or simplex timing chain, which is designed to keep the engine running smoothly for a long time. It has a single row of chain links and is made from high-grade steel, making it more durable and reliable than a belt.
This chain requires less maintenance than a belt and is less likely to break down over time. It’s designed to keep the engine running at optimal temperatures, providing better fuel efficiency and reducing emissions.
Additionally, timing chains are more durable and capable of tolerating the power of turbocharged engines. This ensures a smoother ride and improved driving experience in sports cars, even in the most demanding conditions.
However, make sure you drive safely and if you want to stand on the sunroof of a car while driving, be sure that it’s legal in your area.
Summary:
The BMW X1 has a single-row or simplex timing chain, which is more durable and reliable than a belt. It also minimizes the vibration experienced during engine operation ideal for luxury vehicles.
Can I Use Duplex Chains in the BMW X1?
No, It is not possible to use duplex chains in the BMW X1 because the BMW X1 is not equipped with duplex chain sprockets. Other BMW models come with double-chain supported sprockets where you can install the duplex chains. Duplex chains are more durable than simplex chains and less prone to stretching and wearing.
Can I Use Silent Chains in the BMW X1?
Yes, silent chains can be used on the BMW X1, but it will depend on the drivetrain’s design and power transmission requirements. A BMW dealership or your mechanic can determine if silent chains are feasible for your BMW X1. Also, he/she can advise you on the necessary modifications and installation steps.
FAQs
Why Do Bmw Timing Chains Break?
Timing chains typically break due to wear and tear over time. Another reason is a lack of proper maintenance. Timing chains require very little maintenance, but they shouldn’t be ignored. Also, some BMW models may be prone to timing chain problems due to design flaws or manufacturing defects.
What are the Symptoms Of a Failing Timing Chain?
The common symptoms of a failing timing chain include weird noises in the engine compartment, inability to start the engine, engine misfiring, and engine light indication. If you face any of the symptoms, the timing chain has issues that need attention. Go to the nearest service center or call a mechanic to diagnose and fix this.
Do BMW Petrol Engines Have Timing Chain Problems?
Some BMW engine models like N20,42,43 petrol engines have been known to have timing chain problems. For instance, premature timing chain failure is a serious issue for some BMW models. However, it is essential to note that timing chain problems can occur in any vehicle, regardless of the make or model.
The Bottom Line
That was everything about your query on does BMW x1 have timing belt or chain? I hope you have got all the answers. Always follow the manufacturer’s recommendation and OEM parts to ensure long-lasting and optimal vehicle performance.
I look forward to seeing you at the next one; until then, drive safely.
