Does the N47D20C have timing chain issues?
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 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.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 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.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.
What is the lifetime of the timing chain on a BMW N47?
There is no service schedule for replacing the timing chain, it’s ‘Lifetime’ however is on average around 100,000 miles but that will be heavily dependant on how the car has been maintained from new, we have seen instances of snapped timing chains from 50,000 miles so it is something we strongly recommend you plan to . Unlike timing belts, timing chains do not have a set interval for replacement but may eventually need replacement due to wear and tear. Well maintained engines can go 150,000+ miles on timing chains.How Long Does a Timing Chain Last. Most modern timing chains are designed to last the life of the engine. In many cases, they can go over 150,000 to 200,000 miles without issue, especially if the engine has been properly maintained.How Long Does a Timing Chain Last.

What years were N47 timing chains affected?
n47 timing chain issue the issue applies to all applications and power variants of the engine produced from 01. The most seriously affected units which require the most extensive repairs were produced from 01. 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.
Can you change the N47 timing chain without removing the engine?
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. 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.N47 timing chain recall – BMW 3-Series and 4-Series Forum (F30 / F32) | F30POST.

Because the chain sits at the rear of the engine, replacement is extremely labour-intensive and costly.
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 B57D30B is widely considered the most reliable BMW diesel engine today. It’s a 3. L inline-six with modern technology, a long-lasting timing chain design, and low failure rates. It’s built for high mileage and smooth power delivery, making it perfect for daily use, long trips, and even towing.Problematic BMW Engines with a Reputation for Breaking Down Some specific engine issues have been observed in the BMW 320d 2. Diesel, 520D 2. Diesel, and X5 330D 3. Diesel variants. The BMW 320d 2. Diesel engines, particularly the N47D20A and N47D20C variants, have been prone to timing chain problems.BMW replaced the M57 with the N57 in 2008. While the newer engine brought more power, better emissions compliance, and lighter weight, it also came with known issues: timing chain failures being the most famous. The M57 engine, by contrast, is widely considered more reliable and easier to work on.Models equipped with inline-six engines like the M54, N52, or B58—and diesel workhorses like the M57 or B57—frequently reach 300,000 miles or more. From million-mile E30s tested under lab conditions to 500,000+ mile M5s driven daily, the high-mileage BMW isn’t a myth—it’s a well-documented reality.The N47 engine’s technological features contributed significantly to BMW’s diesel engine development: Efficient Variable Geometry Turbocharging: Improved low-end torque and throttle response. Double-VANOS: Enhanced fuel economy and reduced emissions.
