N47 Engine Problems

For many potential BMW owners, particularly those considering a pre-owned BMW X3 2.0d, there’s a looming question: is the n47 engine a reliable choice? Based on varied opinions from BMW owners, let’s delve into this engine’s main concerns and potential solutions.

The Concerns:

1. Timing Chain Issue: The most frequently discussed problem with the N47 engine is its timing chain failure. This issue is so prevalent that BMW had to issue a recall for the timing chain gear. The failure of this component can lead to significant engine damage and costly repairs.
2. Fuel Pump and Injectors: Although less common than the timing chain problem, there have been reports of issues with the fuel pump and injectors.
3. Catastrophic Failure Before 2011: Engines manufactured before 2011 are particularly at risk of catastrophic timing chain failure.

Solutions:

1. BMW Recall: BMW’s recall for the timing chain gear is still active for certain vehicles. Owners of cars with the N47 engine should check to see if their vehicle qualifies for this recall. Once the timing chain gear is replaced with the updated component, the risk of failure is substantially reduced. It is believed that many N47-equipped cars have already gone through this recall.
2. Replace the Timing Chain Immediately After Purchase: If considering buying a BMW equipped with an N47, particularly a model produced before 2011, it’s recommended to replace the timing chain immediately upon purchase, even if there’s no apparent issue. This proactive step can save significant expenses and potential headaches down the line.
3. Regular Maintenance: Like all engines, the N47 benefits from regular maintenance. Regular oil changes and attention to gasket leaks can go a long way in prolonging the life of the engine.
4. Gearbox Recommendations: For potential BMW X3 buyers, when considering the gearbox, the automatic transmission offers decent performance. Some users reported the auto gearbox can sometimes be slow to change gears at lower speeds but shifts well when accelerating to highway speeds. For those desiring a more hands-on driving experience, the manual gearbox provides a more connected feel, although one should not expect it to handle like sportier BMW models.
5. Engine Revisions Post 2011: According to some users, BMW revised the N47 engine after 2011 to address the catastrophic timing chain failure, further enhancing its reliability. By 2013-2015, the engine underwent additional improvements, cementing its reputation as one of BMW’s more reliable engines in recent years.

Final Thoughts:

While the N47 has had its share of problems, particularly with its timing chain, proper attention and proactive care can mitigate these issues. For those considering an N47-equipped BMW, knowledge of its challenges and the steps to address them can lead to a rewarding ownership experience. However, like all vehicle purchases, individual research and a thorough inspection of any specific car under consideration are essential.
