Signs and Symptoms of a Bad Turbocharger
Assuming that you aren’t a car enthusiast who knows their way around cars, let’s first explain what a turbocharger or turbo is.
Basically, it is a part that helps boost the power of your engine. Even if you have a smaller engine, you can enjoy more performance benefits without having to deal with the extra financial burden and environmental issues that normally come with larger engines.
How Does a Turbo Work?
Your engine uses a mixture of air and fuel to produce power. A turbo works by adding more air in order to increase the power of your engine (without increasing the costs). By spinning an air pump using the exhaust. The pump pushes all the extra air into your engine’s cylinders and thus delivers greater horsepower.
Turbos are supposed to be long-lasting; however, it is still possible that some damage may happen over time.
Common Warning Signs of Turbocharger Failure
1. Slow Acceleration
2. Burning Oil
3. Excessive Exhaust Smoke
4. Check Engine Light or CEL
On most modern cars, the computer diagnostics will detect a failing turbo resulting in the “check your engine.” With that said, the CEL is displayed for a number of problems, sometimes it warns us of a loose gas cap and sometimes about far more serious issues. One of those more serious issues could be the turbo. It’s best to have a mechanic look at your vehicle if the CEL is displayed.
5. Loud Whining Noise
When the boost is running, a failing turbo could make a loud whining noise. The noise usually sounds like a siren, and it tends to get louder as the problem aggravates. If you notice an unusual noise paired with some of the above symptoms, your turbo might be failing.
An example of what this sounds like can be heard in the video below.
