How much horsepower does a N47D20C have?
Engine Excellence: The N47D20C engine is a 2. It combines high fuel efficiency with robust power. Performance: With approximately 184 horsepower and around 380Nm of torque, this engine ensures a smooth driving experience and impressive acceleration. If you own a BMW with an N47 engine, you may have heard of a recurring problem: timing chain failure. This defect affects many diesel BMW models manufactured between 2007 and 2015 and, if not detected early, can lead to costly repairs, with estimates often exceeding €3.The bmw n47 engine is a 2. It produces between 143 to 204 horsepower and offers a torque range of 290 to 400 nm.Here are some of the most common problems associated with the N47D20C engine: 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.The BMW 320d 2. Diesel engine variants, particularly the N47D20A and N47D20C, are notorious for timing chain failures. These engines, which are found in several BMW models, including the 3 Series and 5 Series, have a reputation for premature timing chain failure due to faulty crankshaft sprockets.
What is the difference between N47 and N47s?
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. 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.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.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.The M47 is an older-generation engine, simpler and more reliable, with a front-mounted timing chain. It is a great choice for those who value reliability and want to avoid costly repairs. The N47 is more dynamic, more fuel-efficient, and more modern, but unfortunately less reliable due to its rear-mounted timing chain.
Which N47 engine fails?
The issue predominantly affects early production N47 engines manufactured before 2008, though later variants remain susceptible. Failure typically occurs between 70,000 and 150,000 miles, regardless of maintenance history, suggesting fundamental design weaknesses rather than purely maintenance-related problems. The biggest concern with the n47 engine is its timing chain. Unlike many engines where the chain lasts the lifetime of the engine, the N47’s chain is prone to premature wear and failure—sometimes as early as 80,000 km.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.A bad timing chain can produce a rattling, whining, or clanking noise, especially when the engine is idling or accelerating. This noise is caused by the chain becoming loose or worn.
What 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. N47 Diesel Inline-4 (2007-2014) Why it’s great: Known for its fuel efficiency and durability, the N47 engine is widely used in diesel models. Later variants of the N47 offer improved reliability, making it a favourite for high-mileage drivers.
Is the N47D20C engine reliable?
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.
Is the N47 or B47 better?
Given the B47 vs N47 comparison, the B47 tends to offer better long-term reliability, particularly if proper maintenance is performed. The N47, however, is known for more costly repairs, especially related to the timing chain and turbocharger. 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. DPF Blockages – A common issue in urban cars.
