Why do turbo’s fail? Overheating

What is overheating?

Overheating is a term used to describe components that have been subjected to abnormally high exhaust temperature or insufficient cooling.

Causes of overheating:

  • Hot shut down
  • DPF issues, such as regeneration, resulting in increased exhaust gas pressure and temperatures which leads to overheating of the turbine side of the turbocharger
  • Remapping, chipping or over-fueling
