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 a number of 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.

Warning signs of turbo failure
There are a variety of symptoms that are commonly associated with turbocharger failure in cars. Carefully analysing the performance of the vehicle while driving helps car owners to spot irregularities and diagnose turbo issues.

1)Poor acceleration
One of the most significant symptoms of a failing turbo is lack of overall power.The car may not accelerate quickly or produce the usual amount of power while on the road. When drivers are operating a car with a failing turbo,they may notice that it is slow to respond and does not reach its optimum speeds as rapidly as before.

2)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.

3)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 to the turbo is the right course of action.

4)Lack of boost
Many turbochargers have a boost gauge, which displays the amount of boost that the turbo is producing.Car owners can 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.

5)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 noise accompanies any additional turbo failure symptoms.
