This BMW 8 Series suffered complete bottom turbo failure after the blades contacted the housing. Learn the warning signs of turbo failure and why immediate repair matters.
This BMW 8 Series came into our Newtownabbey workshop with severe performance issues. On inspection, we found the bottom turbocharger had suffered catastrophic failure. The compressor blades had made contact with the turbo housing, causing extensive internal damage.
Unfortunately, once this happens, the turbocharger is beyond repair and must be replaced.
A turbocharger forces additional air into the engine to increase power and efficiency.
Compressor wheel (blades)
Turbo housing
Shaft and bearings
Oil feed and return system
All of these components must operate with extremely tight tolerances.
The images clearly show severe internal turbo damage.
Compressor blades contacting the housing
Blade tips damaged and worn away
Internal imbalance of the turbo
Risk of metal debris entering the engine
Once the blades hit the housing, the turbo cannot be rebuilt or safely reused.
Turbochargers spin at extremely high speeds.
When blade contact occurs:
The turbo loses balance
Bearings fail rapidly
Metal fragments can enter the intake system
Engine damage becomes a real risk
Continuing to run the engine in this condition can cause significant secondary damage.
If you’re driving around Newtownabbey, Glengormley, Mallusk or Jordanstown, common warning signs include:
