What is the problem with the N47D20C engine?
Injector Problems: Some N47D20C engines have experienced injector-related issues, such as fuel leakage, failure to start, or rough running. Faulty injectors may need to be replaced to restore proper fuel delivery and engine performance. Timing Chain Failure: The N47D20C engine has been plagued by timing chain issues. Premature wear and stretching of the timing chain can occur, leading to engine misfires, rattling noises, and even engine failure. This problem often necessitates the replacement of the timing chain and associated components.The N47 engine design requires the engine to be removed from the vehicle to safely access the timing chain. Here’s why: Limited Access: The timing chain is located deep inside the engine block, behind the crankshaft and camshaft.
Which engine is better, N47 or M47?
If reliability, lower failure risk, and cheaper servicing are priorities, the better choice is the M47 or its later version, the M47N/M47N2. If you care about better performance, quieter operation, and modern technology, you can go for the N47 – but be prepared for possible timing chain failures and high repair costs.

In 2014 it was replaced with the B47.The BMW N47s engine is an upgraded version of the well-known N47 diesel engine, fitted in popular BMW models like the 320d, 520d, and X1. While offering excellent performance and fuel efficiency, it suffers from similar reliability issues as the standard N47 — particularly the infamous timing chain problem.BMW N47 – Diesel with Rear-Mounted Timing Chain In 2007, BMW introduced the N47, a new generation of diesel engines. This engine was quieter, offered better performance, improved refinement, and lower fuel consumption. Power ranged from 116 to over 200 hp, making it very popular among drivers who value performance.What is the main difference between the B47 and N47 engines? The main difference is that the B47 is a newer, more advanced engine with improved fuel efficiency, less turbo lag, and fewer common issues, especially in terms of timing chain failures compared to the N47.
Which N47 engine fails?
The most seriously affected units which require the most extensive repairs were produced from 1 March 2007 to 5 January 2009. However, there have been reports of timing chain failure in BMW diesel engines manufactured until 2015. The N47 engine, used in BMWs from 2007 to 2014, is notorious for timing chain failures due to premature wear, often necessitating a complete engine breakdown as the chain is located at the rear of the engine.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. Depending on the RPM at the time of failure, the engine may or may not be salvageable due to the high possibility of internal engine damage.
Which engine is better, B47 or N47?
While the B47 is more robust than the N47, some common issues can still arise, particularly with higher mileage examples or those that miss service intervals. EGR Valve or Cooler Problems – Known to clog or leak, especially with short-distance driving.

Are BMW V8 engines reliable? Some are, but many V8s in the 5 Series—like the N62 and early N63—are known for high maintenance costs and complex issues.BMW S58 twin turbocharge Inline-6 It is a fast car with excellent performance and one reliable engine. The S58 is the latest engine that follows the B58 engine. Although it is new to the market, it has proven itself to be one of the most capable and reliable engines a BMW can have.
What engine to avoid in BMW?
The N54 engine found in many BMW models is known for developing carbon build-up on the intake valves. This can lead to reduced engine performance, rough idling, and poor fuel efficiency. The BMW N47 engine is a 2. It produces between 143 to 204 horsepower and offers a torque range of 290 to 400 Nm.The current BMW 118d (F20) got the obligatory facelift with new aprons and lamps as well as refreshed motors. BMW uses the two-liter diesel twin-power turbo charging. Thus, the performance increases from 143 hp to 150 hp.
Is the BMW 118d engine reliable?
It’s powered by BMW’s latest B-series engine, including the B47 diesel (118d, 120d) and B38 petrol (118i). These replaced the older N-series units and are shared across many current BMWs. Both engines are known for being smooth, efficient and highly reliable for daily driving.
