The air pump then pushes extra air into the engine's cylinders, allowing them to burn more fuel per second, and produce more power than a normally-aspirated unit. Turbos run at incredibly high speeds up to ,rpm which means they operate under huge pressures and temperatures.
Typically, a turbocharger will be paired with cooling systems to cool the oil and hot air. If you notice that your car isn't accelerating as powerfully as it used to, or is slow to react to your input, this might be a sign that your turbo is failing. Similarly, a turbocharged car that struggles to maintain high speeds or isn't able to reach speeds it once could may be experiencing turbo failure.
One of the unexpected advantages of a turbocharger is that it actually makes the engine quieter because it muffles the sound of air intake. However, if you start to hear a loud, whining noise - a bit like a dentist's drill or police siren - it's a potential symptom of turbo failure. As the fault gets more serious, the noise will get worse.
If you notice a whining from your engine, you should get a professional mechanic to have a look at your car. This could be caused by a crack in the turbo housing or damaged internal seals. If this symptom is caused by the turbocharger, you're more likely to see these discoloured fumes as the engine revs increase shortly after idling. The computer diagnostics on most modern cars are able to pick up turbo faults and the check engine light will appear on the dashboard to notify the driver.
However, the check engine light doesn't solely indicate turbo failure - you will need a professional mechanic to perform further checks to diagnose the exact nature of the engine problem.
As it fails, the engine will unfortunately ingest all the bits and pieces that are cast off from the explosive event, netting an outright financial disaster. You need to err on the side of caution on this one and repair the vehicle. This is one of those times when shopping around for a competitive price is encouraged.

If the casing of your turbocharger cracks or if some internal seals are worn out, it could cause the oil to leak into your exhaust. Loss of Power. Increased Oil Consumption. Loud Siren Noise. Check Engine Warning Lights. The Boost Gauge. 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.
Irregular or excessive exhaust. Check engine light. Lack of boost. Loud shrieking noise. Build-up of debris. Cracks or faulty seals. Carbon deposits. A blocked DPF prevents exhaust gas passing through the exhaust system at the required rate. Increased exhaust gas temperature and back pressure can affect the turbocharger in a number of ways, including problems with efficiencies, oil leaks, carbonisation of oil within the turbo and exhaust gas leaks from the turbo.
So a diesel engine without a turbo doesn't make much power and if you try to adjust the fuel or timing to add power, you can only go so far before the lack of air becomes a problem.
This is why all modern diesels use turbochargers. Usually when a turbo fails the pieces go into the intercooler along with a good amount of engine lube oil. The engine can actually run on this spilled oil and "run away.
In most cases, a turbocharger can be repaired , unless the outer housings are damaged. A lack of power, noisy performance or excessive smoke or oil consumption could result from a faulty fuel injection system, restricted or blocked air filters, a damaged exhaust system or a lubrication problem.
Before replacing a turbocharger, it is important to conduct a thorough diagnostic check of the engine systems.
