If you're searching for BMW timing chain replacement cost, it is important to understand that there is no single fixed price for this repair. The exact cost depends on your BMW model, engine type, timing chain design, mileage, and the condition of the engine components.
At Bimmer Garage Nottingham, we specialise in BMW and MINI diesel timing chain inspections and replacements, helping customers identify timing chain problems before they result in major engine damage.
Does BMW Use a Timing Chain?
Most modern BMW engines use a timing chain rather than a timing belt.
BMW diesel engines commonly fitted with timing chains include:
- M47
- N47
- M57
- N57
- B37
- B47
- B57
The repair process varies significantly depending on the engine design.
BMW Engines Known for Timing Chain Concerns
BMW N47 Diesel Engine
The N47 2.0 diesel engine is one of the BMW engines most associated with timing chain wear.
Common models include:
- BMW 116d
- BMW 118d
- BMW 120d
- BMW 318d
- BMW 320d
- BMW 518d
- BMW 520d
- BMW X1 and X3 diesel models
The chain is located at the rear of the engine, making replacement more complex.
BMW N57 Diesel Engine
The N57 3.0 diesel engine is generally strong and reliable, but timing chain wear can occur, especially on higher-mileage vehicles.
Found in models such as:
- BMW 330d
- BMW 530d
- BMW 535d
- BMW X5 diesel models
BMW B47 Diesel Engine
The B47 replaced the N47 and introduced improvements, but correct servicing and regular oil changes remain important for long-term reliability.

If you experience any of these symptoms, a professional inspection is recommended.
Why Do BMW Timing Chains Wear?
Timing chain wear can be caused by:
- Extended oil service intervals

- Low engine oil level

Regular maintenance is one of the best ways to protect your engine.

Early diagnosis can help prevent expensive engine repairs.
