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. Common symptoms of bmw n47 timing chain problems 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 rattle is typically caused by a stretched chain, worn guides, or a failing tensioner.BMW 120D N47 Timing Chain Replacement FAQs Engine-out BMW 120D timing chain replacement typically costs £4,000–£6,500 depending on damage and parts needed.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 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.
What is the weak point of the N47?
The major weak point of the N47 engine is the timing chain. It should be replaced early to avoid engine damage. The chain’s role is to synchronize the pistons and valves. If it breaks, valves collide with pistons, causing immediate engine damage. The B58 engine has earned a stellar reputation since its 2015 introduction. Unlike earlier BMW turbocharged engines like the N54 and N55, the B58 resolved many chronic reliability issues while delivering smooth, responsive power.The M57 (1998-2013) is the most reliable BMW diesel engine, followed by the modern B47 (2014-present). Avoid the N47 (2007-2014) due to timing chain failures unless replaced, and approach the N57 (2008-2020) with caution due to rear-mounted timing chain replacement costs exceeding £2,000.The BMW B47 diesel engine replaced the N47 in 2014, fixing timing chain issues while improving reliability, efficiency, and tuning potential.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 B47 or N47 better?
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. Once the timing chain gear has been replaced with the upgraded components, the N47 becomes a pretty reliable engine if maintained decently, such as oil changes and taking care of gasket leaks. In all honesty, it wouldn’t surprise me if most cars fitted with the N47 have been through the recall already.The only reliability difference between them n57 u can hear the chain rattling , while n47 suddenly can broke and u have to prevent trouble. Louis Geldy Geldart yes it does.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.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.
