The BMW N47 engine is a popular diesel engine used in many BMW models. It first appeared in 2007 and was designed to be efficient, powerful, and reliable. The engine comes in different versions, with different power outputs, ranging from 114 to 204 horsepower. It is a four-cylinder engine and is known for its good fuel economy and performance.
One of the key features of the engine is its turbocharger. This helps the engine produce more power without using more fuel. The engine also uses a common rail direct injection system, which improves fuel efficiency and reduces emissions.
However, the engine has had some issues that owners should be aware of. One of the most common problems is the timing chain. In some cases, the timing chain can wear out or break, causing serious engine damage. BMW has made improvements to the design over the years, but it is still something to keep in mind if you own or are considering buying a car with an N47 engine.
Despite these issues, the engine is well-regarded for its balance of performance and efficiency. It has been used in a wide range of BMW models, including the 1 Series, 3 Series, and 5 Series, as well as in some MINI models. With proper maintenance, the engine can provide many years of reliable service. If you are considering a car with this engine, make sure to check its service history and be aware of the timing chain issue.
