Faulty TurboChargers

What Are The Signs Of Turbo Failure

A turbocharger, or turbo, forces air into a car’s combustion chamber to make the vehicle more powerful. Installing this car part improves speed and performance, but a faulty turbo can lead to expensive repairs. There are some warning signs that indicate that it is time to replace or repair a turbocharger, which can help car owners to avoid the time and expense of severe damage to the vehicle.

The first signs before turbo failing are-

Poor acceleration

One of the most significant symptoms of a failing turbo you should notice is lack of overall power. The car may not accelerate quickly or produce the usual amount of power while on the road. When you are driving a car with a failing turbo, you may notice that your car is slow to respond and does not reach its optimum speeds as rapidly as before.

Irregular or excessive exhaust

An excessive amount of exhaust fumes or grey smoke expelled from the exhaust pipe may be a sign that it is time for a new turbocharger. A crack in the turbo housing can cause oil to leak into the exhaust system, which produces irregular gases.

Check engine light

In many instances, the engine sensor detects a failing turbocharger, triggering the check engine light on the dashboard. An illuminated check engine light may be an indication that further inspection is necessary to determine whether a repair or replacement of the turbo is required.

Lack of boost

Some of the turbochargers, more likely sports cars, have a boost gauge, which displays the amount of boost that the turbo is producing. If your car is one of those, then you can just look at the boost gauge to determine if the turbo is creating the right amount of boost and if it is rising much slower than usual, a replacement turbocharger may be necessary.

Loud shrieking noise

If a turbo is failing, it may produce a noise when the boost is running. The noise comes directly from the engine and sounds like a loud siren or shriek, which tends to get louder as the problem worsens. Any unusual noise under the car’s bonnet is worth investigating, especially if the sound accompanies any additional turbo failure symptoms.

Normal wear and tear

Even with proper maintenance and care, a turbocharger endures wear and tear over time. The lifespan of a turbo dramatically depends on the driving habits of the car’s owner, the quality of the turbo part, and the make and model of the vehicle. The typical turbocharger has a lifespan of about 120,000 kilometers. However, car owners can check the manufacturer’s information to verify how long their turbo may last before it becomes faulty.
