Is the BMW 520d a good engine?
The bmw 520d blends impressive fuel efficiency, respectable performance and refined comfort. Its latest b47 engine addresses the timing chain issues of earlier models and, with proper maintenance, it can surpass 200,000 miles. Powering this 520d is the same 4 cylinder 1,995cc n47 diesel engine which was also in the f30 320d.The 320 and the 520 both use the same 2. In recent years, more buyers have been opting for petrol power. In the case of the 20i engine, both cars get 184hp. They’re punchy, but they’re less efficient than the diesels.
What are common problems with the 520d?
Potential engine issues in older models: Early N47-powered 520d cars (built before 2014) can suffer timing chain stretch, EGR valve clogging and turbocharger wear. Models from this era suffer from a specific problem, the N47 engine has a weakness; basically the power plant is prone to excessive timing chain wear. Throughout 2013 and 2014 BMW owners have reported numerous cases of engine failures, many of which led to terminal decline.What BMW engine should I avoid? Avoid the N63 4. L V8 (2008-2013) due to severe oil consumption and £10,000+ repair costs. The N47 2. L diesel (2007-2014) should be avoided unless timing chain replacement is documented.Repairing or replacing the timing chain on a BMW N47 can be costly due to the labor-intensive process, often ranging from $1,000 to $3,000 depending on the workshop and region. What preventative maintenance can help avoid N47 engine repairs?BMW N47 is a four-cylinder common rail diesel engine that has many improvements over its predecessor, the M47.

Is the N47 engine reliable?
N47 Reliability: Timing Chain Failures: The most significant issue with the N47 is the timing chain. Many owners have reported premature timing chain failures, which can lead to catastrophic engine damage if not addressed in time. This issue is especially common in engines with higher mileage (over 100,000 miles). For modern efficiency and lower running costs, the B47 (2014-present) offers the best balance of performance and reliability, while the N47 should be approached with caution due to well-documented timing chain failures affecting 2007-2014 models.One of the most significant advantages of the N57 is its robust design. It is generally considered to be more reliable than the N47, with fewer common problems. While it’s not entirely immune to issues, the N57 is less prone to the critical failures that plague the N47.
What are common 520d problems?
BMW 520d (N47 & B47 Engines) Timing chain issues: Located at the back of the engine, making replacement costly. A rattling noise on cold start is the first warning sign. EGR valve & DPF clogging: Frequent short trips can lead to carbon buildup, resulting in loss of power and check-engine lights. If you drive a BMW with the N47 engine and hear a metallic rattle on cold starts or when idling, your timing chain might be on its way out. This engine is known for early timing chain wear, particularly on models between 2007 and 2015, and waiting too long can lead to catastrophic engine failure.N47 engine reliability problems One of the most notorious problems with the N47 engine is timing chain failure . Located at the rear of the engine, it is difficult to access, making repairs particularly expensive. A rattling noise coming from the rear of the engine is often an early sign of premature wear.Common Failures in the BMW N47 Engine Early symptoms often start with a distinctive rattling noise on cold starts, sounding like a diesel engine with loose marbles inside. This is usually the plastic timing chain guides degrading and cracking over time, typically between 60,000 and 100,000 miles.The N47 had the timing chain placed at the rear of the engine as BMW felt that access to it would not be needed for the life of the vehicle. BMW usually consider lifetime to mean 100,000 miles. Replacement of the timing chain on the 1 series, 3 series and 5 series engines normally require removal of the engine.Timing chain problems can manifest through several symptoms, including poor engine performance, rough idling, and unusual noises from the engine compartment. In BMW and MINI vehicles, certain models and engine types are particularly susceptible to these issues.
