Automobile manufacturers utilize an additional device called a turbocharger, or simply a turbo, to increase engine power. The same amount of power that is often found in larger cars is frequently delivered in smaller cars via the employment of turbos.

These days, almost every manufacturer has a turbocharged variant available. It means they can provide smaller engines that produce the same power output while also increasing fuel efficiency. For instance, Ford switched out their previous 1.6-liter petrol engine for a new 1.0-liter turbo EcoBoost engine.

But now the question is, what happens when this component goes bad? Let’s find out!


Symptoms Of A Bad Turbo Charger

Symptoms of a bad Turbo Charger

Power Break

Your car may be experiencing a failing turbo if you notice that it isn’t responding to your inputs as quickly or as forcefully as it used to. Similar to this, a car with a turbocharger that finds it difficult to maintain high speeds or that can no longer achieve speeds could be having turbo failure.

Engine Whining

One unforeseen benefit of a turbocharger is that it decreases the noise from the air intake, resulting in a quieter engine. On the other hand, a loud, whining noise that sounds like a police siren or a dentist’s drill could be a sign of a turbo failure. The noise level will increase if the problem becomes more severe. You should have your car inspected by a qualified mechanic if you hear your engine complaining.

Smoke from the Exhaust

A distinctive blue-gray smoke is released as oil leaks into the exhaust system and burns off. Damage to internal seals or a crack in the turbo housing could be the cause of this. The turbocharger is more likely to be the source of this symptom if you notice these colored pollutants soon after the engine starts up.

Check Engine Light

Most present cars have computer diagnostics that may identify turbo defects; the driver is made aware of these faults by a check engine light that appears on the dashboard. The check engine light does not, however, only signal a problem with the turbo; additional testing must be done by a qualified mechanic to determine the exact nature of the engine issue.


If your turbocharger fails, you will still be able to drive your car; however, engine failure will be fast approaching, so only drive if necessary. If you see any of the above-mentioned turbo failure signs, you should have a skilled technician inspect your turbo as soon as possible. The longer you leave it, the worse (and more expensive) the situation will get.
