Our experienced BMW technicians carry out preventative timing chain replacement and complete timing chain failure repairs using genuine OE-quality components.
What Is The BMW N57 Engine?
The BMW N57 is a 2993cc six-cylinder turbo diesel engine featuring:
- Aluminium block and cylinder head
- Common rail direct injection
- Variable geometry turbochargers
- Single turbo, twin turbo and tri-turbo variants
- Power outputs from 204bhp to over 380bhp
The N57 replaced the legendary M57 engine and was later succeeded by the B57 engine.
Many BMW enthusiasts consider the N57 one of the best diesel engines BMW has ever produced due to its combination of power, refinement and fuel economy.
Signs Your N57 Timing Chain Needs Replacing
Early diagnosis can save thousands in repair costs.
What Happens If An N57 Timing Chain Fails?
A snapped timing chain can cause severe internal engine damage.
Typical damage includes:
