All manufacturers sell their new cars with turbocharged model now. It means they can use the smaller engine but still produce the same power output and your car also has higher performance.


Nowadays, turbo is a common system used by car manufacturers to boost engine power, maintain low engine liters and also lower the fuel tax. Turbos are widely used to release the same level of power in smaller cars that's usually found in larger cars.


Engine mixture the fuel and the air to produce power to drive the wheels so the car can move, and the function of turbo is that run at incredibly high speeds to add more air into the mixture by using the exhaust to spin an air pump, then the air pump pushes extra air which turbo exhausted into the engine's air cylinder, so the engine can burn more fuel, and produce more power than a naturally aspirated engine.

What causes turbo failure?

Turbo failure is normally the result with engine lubrication problem or damage from the external substance. Basically, the turbochargers are pretty reliable now. In fact, less than 1% of warranty inspection finds the faulty with the turbo itself.


1.Lack of oil and lubrication cause serious gear wearing

It's important that the engine oil and oil filter are both replaced at the manufacturer's recommended intervals. Turbo needs a good flow of clean oil to keep it working properly. Oil works to lubricate key moving parts, protect them from corrosion and keep them cool while in use. A lack of oil (oil starvation), incorrect grade of oil or poor-quality oil will lead your turbo suffer from a build- up of the carbon deposits & contaminants. Then reduce its effectiveness and even cause it to completely break down over time. It can cause a bad damage inside the turbo.


2.External substance cause a big damage

A turbocharger is virtually made of two fundamental components: the compressor at the front and the turbine at the back. If the external substance enters the compressor housing, like dead bug or dust, it often comes from the air filter.
In contrast, if the external substance causes damage to the turbine, the substance usually comes from the engine itself.


Sometimes, external substance such as dust particles, dirt, leaves and small stones can enter the turbo, either via the compressor inlet or turbine inlet and the efficiency of the turbo will be reduced if foreign objects start to damage the compressor wheels or turbine blades.
These particles can cause severe damage to the wheels and blades in the turbo. To prevent this happening, check your air filter is serviced and replaced regularly. Also, check your turbo for debris at the same time.



3.Aging can cause many problems

A turbo's life-cycle is around 100K to 150K miles, it's possible for them to wear out over time depending on how hard you drive the car. Although the turbo is stable but it will not last forever. It will need replacing eventually.

So once again, remember to have the regular maintenance for your turbo.


4.Don’t be a crazy driver and over-speeding all the time

Continually pushing at the top levels of your engine’s performance will force gas through the seals and pipes. As the turbocharger is constantly under pressure, there are many things that can impact its performance. Over time this pressure can cause leaks and cracks, making the turbo work harder and increasing levels of fatigue.


Signs of a Failed Turbo


This could be caused by a crack in the turbo housing or damaged internal seals. The worn seals and cracks in the turbo will allow oil leak gets into the exhaust, which will burn with a very distinct greyish blue smoke. You will see these dirty fumes increase as the engine starts after idling. This symptom becomes even more extraordinary when you’re driving at high speed and boosting the turbo.

So if you notice this smoke from your parking mirror then you may get the idea that the turbo could be the main reason.



Another advantage of a turbocharger is that it actually makes the engine quieter than the natural aspirated engine because it covers the noise of air intake. So, if you start to hear a loud, whiing noise that came from your turbo (a bit like a dentist's drill or police siren), your turbocharger probably broken. As the faulty gets more serious, the noise will get worse, you should get a professional mechanic to have a look at your car.



Modern cars are able to pick up turbo faults and the check engine light will appear on the dashboard to remind the driver. However, there are several reasons why this light occurs on your dashboard. It could be down to problems with your sensors, or even a loose petrol cap, but sometimes it may represent a serious problem with your turbo.
Consider of the driving safety; get to the repair shop to check out soon.
You will need a professional mechanic to perform further checks to find out the exact issue of the engine problem.


  1. BURNING OIL or Oil Leaking

As we mentioned before, turbo works at high temperature so if there is any deposit or oil leaking in the pipe, it will cause oil burning. When this happened, you should disconnect the downpipe at the front of the turbo and take a look inside to check if there is any oil deposit.
Oil leaking is a big issue for turbocharger. You need to get the repair shop for turbo serviced. If you don’t care about this issue and leave unchecked the entire system would probably fail.


  1. Power Loss

Turbocharger is used to make your car faster and more dynamic. Usually you will become very aware of its performance and capabilities. So, if you notice that your car isn't accelerating as powerful as it used to, hard to maintain high speeds, difficult to reach speeds, or is slow to react to your throttle, this might be a sign that your turbo is failing.
If you notice any of these symptoms, checking the turbo should be your first option.

Can I drive with a broken turbo?

Believe it or not, you can still drive on without the turbo, but it is probably safer to call for a recovery lift. If you decide to drive with a broken turbo, you should unhook the linkage from the wastegate activator first, and then use a wire to hold it open as you drive the necessary distance to get to a mechanics.
Go easy on the throttle as the wastegate won’t be able to handle the full pressure of the exhaust.
(don’t go more than around 100 miles.)

Broken Turbo

The longer you leave it, the worse and more expensive the problem will become, so you should still get your turbo checked as soon as possible by a qualified technician.
