Essential advice for diagnosis and replacement of turbos.
Fault Fact Sheets
When analysing possible turbo-charger problems please remember the following:
- Turbochargers are very reliable: less than 1% of turbos fail due to a manufacturing fault with the turbo itself.
- 95% of turbo failures are because of problems with oil starvation, oil contamination or foreign object damage
- Before you fit a new turbo, find out what caused the first unit to fail or you risk the replacement failing too.
