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 n47 engine is a 2.The BMW N47 and N47TU are both 2. N47TU (Technical Update) introduced several improvements over the original N47.The BMW B47 is a 1,995cc inline-4 turbocharged diesel engine first introduced in 2014. It belongs to BMW’s modular engine family (alongside the B38, B48, and B57) and was designed to replace the ageing N47.In 2014, BMW replaced the N47 engine with the B47 which uses same chain design but left the poor reputation of the N47 behind.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.
Is the N47 twin turbo?
The BMW N47 engine is a 2. It produces between 143 to 204 horsepower and offers a torque range of 290 to 400 Nm. Modern engines can last 300,000 miles or more with proper maintenance, and the timing chain can go that long, too.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.For UK drivers looking for long-term reliability, the M57 engine often comes out on top. However, the N57 offers modern efficiency improvements if you prefer newer BMW models.For BMW and MINI owners, we recommend replacing timing chains proactively after 90,000 miles or 9 years to avoid catastrophic engine failures and costly repairs.The main problems with the N47 timing chain were noted until 2011 although there are still, albeit fewer, reported problems after this. In 2014, BMW replaced the N47 engine with the B47 which uses same chain design but left the poor reputation of the N47 behind.
Is the N47D20C good?
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. The issue is particularly common in BMW models with N47 and N57 diesel engines, typically found in: BMW 1 Series (E81, E82, E87, E88) – 2007-2013. BMW 3 Series (E90, E91, E92, E93) – 2007-2013. BMW 5 Series (F10, F11) – 2010-2016.
Which BMW engine is better, M47 or N47?

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. Yes, given the right care, it is thought to be reliable. It works nicely when serviced properly and is a big step up over the N47.
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. Production Start Date: • The N47 was produced from 2007 to around very end of year 2009 (rare occasions early 2010). The N47TU (Technical Update) was introduced in 2010 and continued until 2014 before being replaced by the B47.
