The BMW N47 is one of BMW's best-known four-cylinder diesel engines. Produced from the late 2000s through much of the 2010s, the N47 was fitted to a wide range of BMW models, from the 1 Series and 3 Series to the X1 and other applications.
For owners considering buying an N47-powered BMW, understanding the engine's specifications and known characteristics is important.
At Bimmer Garage Nottingham, we work with BMW diesel engines and can diagnose and maintain N47-powered vehicles.
BMW N47 Engine Specifications
The N47 is a four-cylinder, inline diesel engine using common-rail direct injection and turbocharging.
Specifications vary significantly depending on the exact engine version, but the N47 family generally covers engines with:
| Specification | BMW N47 |
|---|---|
| Engine type | Inline 4-cylinder diesel |
| Capacity | Approximately 1.6–2.0 litres |
| Fuel system | Common-rail direct injection |
| Aspiration | Turbocharged |
| Valvetrain | DOHC, 16 valves |
| Production | Approx. 2007–2017 |
| Typical power range | Approx. 95–218 hp |
| Typical torque range | Approx. 235–450 Nm |
| Timing system | Timing chain |
| Emissions | Varies by model/year |
The exact specification depends on the engine code, model year and vehicle.
N47 2.0 Diesel
The 2.0-litre N47 is the version most commonly associated with BMW's N47 engine family.
It was offered in different states of tune, with power outputs varying according to application.
Examples include:
- N47D20U0 – lower-output applications
- N47D20K0 – economy-focused versions
- N47D20O0 – higher-output applications
- N47D20T0 – twin-turbo/high-performance application
Power outputs can range from around 143 hp to more than 200 hp, depending on the exact variant.
BMW Models Using the N47
The N47 was fitted to numerous BMW models, including various versions of:
BMW 1 Series
The N47 appeared in models such as the 116d, 118d and 120d, depending on the generation and year.
BMW 3 Series
The engine was widely used in the E90/E91/E92/E93 and later F30 generation, including various 316d, 318d and 320d models.
BMW 5 Series
Certain F10/F11 5 Series models were also available with N47 diesel engines.
BMW X1
The N47 was used extensively in the E84 X1, including various diesel specifications.
Other BMW applications also used versions of the engine.
BMW N47 Torque
One of the reasons the N47 became so popular was its strong low- and mid-range torque.
Depending on the version, torque can range from approximately 235 Nm to 450 Nm.
This gives N47-powered BMWs strong everyday performance while maintaining relatively good fuel economy.
The exact torque figure should always be checked against the specific engine code rather than assuming all N47 engines have the same output.
BMW N47 Timing Chain
One of the most important things to understand about the N47 is its timing chain arrangement.
The timing chain is located at the rear of the engine, towards the gearbox.
This design can make timing-chain repairs considerably more involved than on engines where the chain is positioned at the front.
Timing-chain wear has become one of the best-known concerns associated with certain N47 engines.
Symptoms of N47 Timing Chain Wear
Potential warning signs include:
- Rattling from the rear of the engine
- Metallic noises, particularly during starting
- Timing-related fault codes
- Poor engine running
- Difficulty starting
- Engine management warning
However, not every noise from an N47 indicates timing-chain failure.
If you hear an unusual metallic rattle from the engine, professional diagnosis is recommended.
Is the BMW N47 a Good Engine?
The N47 offers a strong combination of:
- Good fuel economy
- Strong torque
- Compact design
- Good everyday performance
- Wide availability of parts and servicing expertise
However, like any engine, it has known areas that require attention.
Timing-chain condition is particularly important, especially on higher-mileage examples or vehicles without clear maintenance history.
N47 Maintenance
Regular maintenance is essential for long-term reliability.
Important areas include:
- Correct engine oil and regular oil changes
- Timing-chain inspection where appropriate
- DPF condition
- EGR system
- Turbocharger
- Cooling system
- Intake system
- Glow plugs
- Diesel injectors
Using the correct oil specification and maintaining sensible service intervals can help protect the engine and turbocharger.
Buying an N47 BMW?
If you're considering buying a BMW with an N47 engine, don't focus only on mileage.
A higher-mileage car with a strong service history can be a better proposition than a lower-mileage vehicle that has been poorly maintained.
Check for:
- Complete service history
- Evidence of timing-chain work
- Engine noise
- DPF condition
- Turbocharger performance
- Oil leaks
- Diagnostic fault codes
- Previous major repairs
A pre-purchase inspection can potentially identify expensive problems before you commit to the purchase.
